Answer:
Very distrusting but also fearful of one another
Step-by-step explanation:
The Cold War is a phrase meant to describe the period between 1945 (when WWII ended) and 1991 (when the USSR ended). This was a time when America and the Soviet Union were competing to become the world's most dominant country, and also were competing to have their economic systems be the dominant economic system within the world (the US was capitalism and the USSR was communism). During this time there was never directly a fight between the two countries, but they were constantly allying themselves with other countries to become more powerful, building increasingly more dangerous nuclear weapons, spying on one another, and involving themselves in what's called a proxy was (such as the Vietnam war) where they were directly fighting but took opposite sides in an ongoing conflict.
