<span>Remember, at the time, it was the Austro-Hungarian Empire. The Empire (unlike any of the other major states in Europe) was a patchwork of over a dozen major ethnic groups. Nationalism tends to organize along ethnic boundaries (that is, nations tend to form around a large concentration of one ethnic group). Thus, with a very large number of different ethnic groups, the Empire had to worry about each group wanting to split from the Empire, and form its own nation. Indeed, after WW1, this is what happened to the Empire - it was split into about a 8 different countries (or, more accurately, portions of 8 countries included lands formerly part of the Austro-Hungarian Empire).</span>
Answer:
During World War II, the United States and the Soviet Union fought together as allies against the Axis powers. However, the relationship between the two nations was a tense one. Americans had long been wary of Soviet communism and concerned about Russian leader Joseph Stalin’s tyrannical rule of his own country. For their part, the Soviets resented the Americans’ decades-long refusal to treat the USSR as a legitimate part of the international community as well as their delayed entry into World War II, which resulted in the deaths of tens of millions of Russians. After the war ended, these grievances ripened into an overwhelming sense of mutual distrust and enmity.
