Answer:
C
Step-by-step explanation:
Why is it C? Well
A: A is much easier represented with World War I, as although Wilson joined in, he quickly resorted to Isolationism after the war.
B: Although that there were more powers than just the US, there was only one other one, the USSR, as the rest of the nations were either allied to the USSR or allied to the US. Yes, China was its own side after the Sino-Soviet split, but they only managed to recruit Albania
D: In technical terms, yes. There were hundreds of thousands of deaths on both sides. In hindsight, no, because we managed to stop one of the most brutal dictators in history
C: The years that would follow World War II would be known as the cold war, an intense political standoff between the US and USSR, between Communism and Capitalism.
