Washington Naval Treaty, 1922 في معرفة المصادر

مؤتمر واشنطن البحري عقد في مدينة واشنطن دي سي عاصمة الولايات المتحدة الأمريكية لمناقشة مسألة نزع التسلح البحري، ومناقشة مشكلات معينه تشمل آسيا. انعقد المؤتمر في الفترة من نوفمبر 1921م إلى فبراير 1922م ، وكانت الدول الممثلة فيه هي: بلجيكا، الصين، فرنسا، بريطانيا، إيطاليا، اليابان، هولندا، البرتغال، الولايات المتحدة الأمريكية.

انبثقت عن المؤتمر ثلاث معاهدات رئيسية، هي:

  1. معاهدة القيود البحرية للقوى الخمس ـ التي أقرتها كل من بريطانيا وفرنسا وإيطاليا واليابان والولايات المتحدة، وقد أنهت هذه المعاهدة الزيادة المتنامية للسفن الحربية الرئيسية لدى هذه الدول.
  2. معاهدة القوى الأربع التي وقعتها كل من بريطانيا وفرنسا واليابان والولايات المتحدة الأمريكية – وقد اعترفت هذه المعاهدة بامتلاك كل دولة لجزر معينة في المحيط الهادي.
  3. معاهدة القوى التسع التي اشتركت فيها كل الدول المشاركة في المؤتمر، وكان الغرض الرئيسي لها ضمان استقلال الصين، وقد استمر سريان احترام هذه المعاهدة حتى عام 1931م، عندما قامت اليابان بغزو منشوريا، وهي إقليم في شمال شرقي الصين.

خلفية

Immediately after World War I, Britain still had the world's largest and most powerful navy, followed by the United States and more distantly by Japan, France and Italy. The British Royal Navy had interned the defeated German High Seas Fleet. The Allies had differing opinions concerning the final disposition of the Imperial German Navy, with the French and Italians wanting the German fleet divided between the victorious powers and the Americans and British wanting the ships destroyed. The negotiations became mostly moot after the German crews had scuttled most of their ships.

News of the scuttling angered the French and the Italians, with the French particularly unimpressed with British explanations that the fleet guarding the Germans had then been away on exercises. Nevertheless, the British joined their allies in condemning the German actions, and no credible evidence emerged to suggest that the British had collaborated actively with the Germans with respect to the scuttling. The Treaty of Versailles, signed soon after the scuttling of the German High Seas Fleet, imposed strict limits on the size and the number of warships that the newly-installed German government was allowed to build and maintain.[بحاجة لمصدر]

The Americans, the British, the French, the Italians, and the Japanese had been allies during World War I, but with the German threat seemingly finished, a naval arms race between the erstwhile allies seemed likely for the next few years.[1] US President Woodrow Wilson's administration had already announced successive plans for the expansion of the US Navy from 1916 to 1919 that would have resulted in a massive fleet of 50 modern battleships.[2]

In response, the Japanese Diet finally authorised construction of warships to enable the Japanese Navy to attain its goal of an "eight-eight" fleet programme, with eight modern battleships and eight battlecruisers. The Japanese started work on four battleships and four battlecruisers, all of which were much larger and more powerful than those of the classes that they were replacing.[3]

The 1921 British Naval Estimates planned four battleships and four battlecruisers, with another four battleships to follow the subsequent year.[1]

The new arms race was unwelcome to the American public. The US Congress disapproved of Wilson's 1919 naval expansion plan, and the 1920 presidential election campaign caused politics to resume the non-interventionalism of the prewar era, with little enthusiasm for continued naval expansion.[4] Britain also could ill afford any resumption of battleship construction, given the exorbitant cost.[5]

In late 1921, the US became aware that Britain was planning a conference to discuss the strategic situation in the Pacific and Far East regions. To forestall the conference and to satisfy domestic demands for a global disarmament conference, Warren Harding's administration called the Washington Naval Conference in November 1921.[6]

The Conference agreed to the Five-Power Naval Treaty as well as a Four-Power Treaty on Japan and a Nine-Power Treaty on China.[7]


المفاوضات

At the first plenary session held November 21, 1921, US Secretary of State Charles Evans Hughes presented his country's proposals. Hughes provided a dramatic beginning for the conference by stating with resolve: "The way to disarm is to disarm".[8] The ambitious slogan received enthusiastic public endorsement and likely abbreviated the conference while helping ensure his proposals were largely adopted. He subsequently proposed the following:

  • A ten-year pause or "holiday" of the construction of capital ships (battleships and battlecruisers), including the immediate suspension of all building of capital ships.
  • The scrapping of existing or planned capital ships to give a 5:5:3:1.67:1.67 ratio of tonnage with respect to Britain, the United States, Japan, France and Italy respectively.
  • Ongoing limits of both capital ship tonnage and the tonnage of secondary vessels with the 5:5:3 ratio.

Capital ships

The proposals for capital ships were largely accepted by the British delegation. However, they were controversial with the British public. Britain could no longer have adequate fleets in the North Sea, the Mediterranean and the Far East simultaneously, which provoked outrage from parts of the Royal Navy.[بحاجة لمصدر]

Nevertheless, there was huge demand for the British to agree to the limits and reductions: the risk of war with the Americans was increasingly regarded as merely theoretical as there were very few policy differences between the two Anglophone powers; continued naval spending was unpopular in Britain throughout the empire; and Britain was implementing major budget reductions due to the post–World War I recession.[9]

The Japanese delegation was divided. Japanese naval doctrine required the maintenance of a fleet 70% the size of that of the United States, which was felt to be the minimum necessary to defeat the Americans in any subsequent war. The Japanese envisaged two separate engagements, first with the U.S. Pacific Fleet and then with the U.S. Atlantic Fleet. It calculated that a 7:5 ratio in the first battle would produce enough of a margin of victory to be able to win the subsequent engagement and so a 3:5 ratio was unacceptable because a 3:5 total fleet size ratio would imply a 6:5 ratio in the first battle. Nevertheless, the director of the delegation, Katō Tomosaburō, preferred to accept the latter to the prospect of an arms race with the United States, as the relative industrial strength of the two nations would cause Japan to lose such an arms race and possibly suffer an economic crisis. At the beginning of the negotiations, the Japanese had only 55% of the capital ships and 18% of the GDP of the Americans.[بحاجة لمصدر]

Akagi (Japanese ship originally planned as a battlecruiser but converted during construction to an aircraft carrier) in April 1925.

His opinion was opposed strongly by Katō Kanji, the president of the Naval Staff College, who acted as his chief naval aide at the delegation and represented the influential "big navy" opinion that Japan had to prepare as thoroughly as possible for an inevitable conflict against the United States, which could build indefinitely more warships because of its huge industrial power.[بحاجة لمصدر]

Katō Tomosaburō was finally able to persuade the Japanese high command to accept the Hughes proposals, but the treaty was for years a source of controversy in the navy.[10]

The French delegation initially responded negatively to the idea of reducing their capital ships' tonnage to 175,000 tons and demanded 350,000, slightly above the Japanese limit. In the end, concessions regarding cruisers and submarines helped persuade the French to agree to the limit on capital ships.[11]

Another issue that was considered critical by the French representatives was the Italian request of substantial parity, which was considered to be unsubstantiated; however, pressure from the American and the British delegations caused the French to accept it. That was considered a great success by the Italian government, but parity would never actually be attained.[12]

There was much discussion about the inclusion or exclusion of individual warships. In particular, the Japanese delegation was keen to retain their newest battleship Mutsu, which had been funded with great public enthusiasm, including donations from schoolchildren.[13] That resulted in provisions to allow the Americans and the British to construct equivalent ships.[بحاجة لمصدر]

Cruisers and destroyers

Hughes proposed to limit secondary ships (cruisers and destroyers) in the same proportions as capital ships. However, that was unacceptable to both the British and the French. The British counterproposal, in which the British would be entitled to 450,000 tons of cruisers in consideration of its imperial commitments but the United States and Japan to only 300,000 and 250,000 respectively, proved equally contentious. Thus, the idea of limiting total cruiser tonnage or numbers was rejected entirely.[11]

Instead, the British suggested a qualitative limit of future cruiser construction. The limit proposed, of a 10,000 ton maximum displacement and 8-inch calibre guns, was intended to allow the British to retain the Hawkins class, then being constructed. That coincided with the American requirements for cruisers for Pacific Ocean operations and also with Japanese plans for the Furutaka class. The suggestion was adopted with little debate.[11]

Submarines

A major British demand during the negotiations was the complete abolition of the submarine, which had proved so effective against them in the war. That proved impossible, particularly as a result of French opposition, which demanded an allowance of 90,000 tons of submarines,[14] and the conference ended without an agreement to restrict submarines.[15]

Pacific bases

Article XIX of the treaty also prohibited the British, the Japanese and the Americans from constructing any new fortifications or naval bases in the Pacific Ocean region. Existing fortifications in Singapore, the Philippines and Hawaii could remain. That was a significant victory for Japan, as newly-fortified British or American bases would be a serious problem for the Japanese in the event of any future war. That provision of the treaty essentially guaranteed that Japan would be the dominant power in the Western Pacific Ocean and was crucial in gaining Japanese acceptance of the limits on capital ship construction.[16]

الآثار

The treaty arrested the continuing upward trend of battleship size and halted new construction entirely for more than a decade.

The treaty marked the end of a long period of increases of battleship construction. Many ships that were being constructed were scrapped or converted into aircraft carriers. Treaty limits were respected and then extended by the London Naval Treaty of 1930. It was not until the mid-1930s that navies began to build battleships once again, and the power and the size of new battleships began to increase once again. The Second London Naval Treaty of 1936 sought to extend the Washington Treaty limits until 1942, but the absence of Japan or Italy made it largely ineffective.

There were fewer effects on cruiser building. The treaty specified 10,000 tons and 8-inch guns as the maximum size of a cruiser, but that was also the minimum size cruiser that any navy was willing to build. The treaty began a building competition of 8-inch, 10,000-ton "treaty cruisers", which gave further cause for concern.[17] Subsequent naval treaties sought to address that by limiting cruiser, destroyer and submarine tonnage.

Unofficial effects of the treaty included the end of the Anglo-Japanese Alliance. Although it was not part of the Washington Treaty in any way, the American delegates had made it clear that they would not agree to the treaty unless the British ended their alliance with the Japanese.[18] The 1921 Imperial Conference earlier in the year had already decided not to renew the Alliance.[19]

المخالفات

In 1935, the French Navy laid down the battleship Richelieu; combined with the two Dunkerque، طراز battleships also under construction, which placed the total tonnage over the 70,000-ton limit on new French battleships until the expiration of the treaty. The keel laying of Jean Bart in December 1936, albeit less than three weeks before the treaty expired, increased the magnitude of France's violation by another 35,000 tons. The French government dismissed British objections to the violations by pointing out that Britain had signed the Anglo-German Naval Agreement in 1935, which unilaterally dismantled the naval disarmament clauses of the Treaty of Versailles. German naval rearmament threatened France, and according to the French perspective, if Britain freely violated treaty obligations, France would similarly not be constrained.[20]

Italy repeatedly violated the displacement limits on individual ships and attempted to remain within the 10,000-ton limit for the Trento، طراز cruisers built in the mid-1920s. However, by the Zara، طراز cruisers in the late 1920s and early 1930s, it had abandoned all pretense and built ships that topped 11,000 long tons (11,000 t) by a wide margin. The violations continued with the Littorio، طراز battleships of the mid-1930s, which had a standard displacement in excess of 40,000 long tons (41,000 t). The Italian Navy nevertheless misrepresented the displacement of the vessels as being within the limits imposed by the treaty.[21]

Japanese denunciation of the Washington Naval Treaty, 29 December 1934

The naval treaty had a profound effect on the Japanese. With superior American and British industrial power, a long war would very likely end in a Japanese defeat. Thus, gaining strategic parity was not economically possible.[22]

Many Japanese considered the 5:5:3 ratio of ships as another snub by the West, but it can be argued that the Japanese had a greater force concentration than the US Navy or the Royal Navy. The terms also contributed to controversy in high ranks of the Imperial Japanese Navy between the Treaty Faction officers and their Fleet Faction opponents, who were also allied with the ultranationalists of the Japanese army and other parts of the Japanese government. For the Treaty Faction, the treaty was one of the factors that had contributed to the deterioration of the relationship between the American and the Japanese governments.

Some have also argued that the treaty was one major factor in prompting Japanese expansionism by the Fleet Faction in the early 1930s. The perception of unfairness resulted in Japan's renunciation of the Second London Naval Treaty in 1936.

Isoroku Yamamoto, who later masterminded the attack of Pearl Harbor, argued that Japan should remain in the treaty. His opinion was more complex, however, in that he believed the United States could outproduce Japan by a greater factor than the 5:3 ratio because of the huge American production advantage of which he had expert knowledge since he had served with the Japanese embassy in Washington. After the signing of the treaty, he commented, "Anyone who has seen the auto factories in Detroit and the oil-fields in Texas knows that Japan lacks the power for a naval race with America." He later added, "The ratio works very well for Japan – it is a treaty to restrict the other parties."[23] He believed that other methods than a spree of construction would be needed to even the odds, which may have contributed to his advocacy of the plan to attack Pearl Harbor.

On December 29, 1934, the Japanese government gave formal notice that it intended to terminate the treaty. Its provisions remained in force formally until the end of 1936 and were not renewed.[24]

تأثير فك الشفرات على المعاهدة

ما لم يكن معروفاً للمشاركين في المؤتمر هو أن الغرفة السوداء الأمريكية في مدينة نيويورك، تحت إمرة هربرت ياردلي، كانت تتجسس على اتصالات الوفود مع عواصمهم. وعلى الأخص، فإن اتصالات اليابانيين كان مخترقة بالكامل، وقد تمكن المفاوضون الأمريكان من معرفة الحد الأدنى المقبول لليابانيين والذي دونه كانوا سيغادرون المؤتمر. ولما كانت هذه النسبة غير مقبولة لمعظم قادة الأسطول الياباني الإمبراطوري، وكذلك غير مقبولة للجماعات المفرطة الوطنية التي أخذت أسهمها في الصعود، فإن القيمة التي قبلت بها الحكومة اليابانية كانت سبباً في الكثير من الشك والاتهامات في اليابان بين السياسيين والضباط البحريين.
