Can someone please help me with this???

Explanation:

One big thing was the Arms Race

While Russia had no strict human rights policy and favored economic advantage, US was falling behind and their economic policy differed from Russia’s in many ways. One specific instance of the two fighting was the Cuban Missile Crisis. The USSR thought that they should stake missiles in Cuba to ward off the lead the US was obtaining in missiles and such. This example shows just how deadly the feud between Russia and the US was mainly because their economic goals differed. (Communism vs capitalism)
