arrived in Taiwan on January 23, 1954, and were immediately celebrated as "Anti-Communist volunteers". The ROC government soon declared January 23 as World Freedom Day in their honor. Soviet Union The war was a political disaster for the Soviet Union. Its central objective, the unification of the Korean peninsula under the Kim Il-Sung regime, was not achieved. Boundaries of both parts of Korea remained practically unchanged. Furthermore, relations with communist ally China were seriously and permanently spoiled, leading to the Sino-Soviet split that lasted until the collapse of the Soviet Union in 1991. The United States' strong resistance to the invasion may have prevented a Soviet intervention in Yugoslavia during the Tito–Stalin split. The war, meanwhile, united the countries within the capitalist bloc: the Korean War accelerated the conclusion of a peace agreement between the U.S. and Japan, the warming of West Germany's relations with other western countries, creation of military and political blocs ANZUS (1951) and SEATO (1954). However, because of the war, the authority of the Soviet State grew, which showed in its readiness to interfere in developing countries of the Third World, many of which after the Korean war went down the socialist path of development, after selecting the Soviet Union as their patron. It is generally assumed that the war was a heavy burden on the national economy of the Soviet Union, which was still suffering from the effects of World War II. Expenditures for defense certainly grew more sharply than they otherwise would have. However, it has been claimed that in fact much of the payment for the Soviet contribution to the war effort was made by China (which perhaps goes some way towards explaining the eventual split between the two countries). Also, some historians believe, instead of an obvious political disaster, the war actually may have served to preserve the military power of the Soviet Union, while western forces became relatively broken. Despite the expenses and regardless of who paid them, it must also be said that the Korean War provided approximately thirty thousand Soviet military personnel valuable experience in waging local wars. The conflict also allowed the Soviets the opportunity to test several new forms of armament, in particular the MiG-15 combat aircraft. Furthermore, numerous models of American military equipment were captured, which made it possible for Soviet engineers and scientists to reverse engineer American technology, and use what they learned for the
