Cuba, officially the Republic of Cuba is a country comprising the island of Cuba, as well as Isla de la Juventud and several minor archipelagos.
Since 1965, the state has been governed by the Communist Party of Cuba. The country was a point of contention during the Cold War between the Soviet Union and the United States, and a nuclear war nearly broke out during the Cuban Missile Crisis of 1962.
Culturally, Cuba is considered part of Latin America.
The Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a federal socialist state in Northern Eurasia that existed from 1922 to 1991. Nominally a union of multiple national Soviet republics, it was a one-party state (until 1990) governed by the Communist Party, with Moscow as its capital in its largest republic, the Russian SFSR.
The Soviet Union had its roots in the October Revolution of 1917 when the Bolsheviks, headed by Vladimir Lenin, overthrew the Provisional Government that had earlier replaced the monarchy of the Russian Empire.
On 25 December 1991, Gorbachev resigned and the remaining twelve constituent republics emerged from the dissolution of the Soviet Union as independent post-Soviet states. The Russian Federation (formerly the Russian SFSR) assumed the Soviet Union’s rights and obligations and is recognized as its continued legal personality.
