Question

what is the reason for cold war and tell the year of cool war​

Answer 1

Answer:

The first phase of the Cold War began immediately after the end of the Second World War in 1945. The United States created the NATO military alliance in 1949 in apprehension of a Soviet attack and termed their global policy against Soviet influence containment.

Answer 2

The period is generally considered to span the 1947 Truman Doctrine to the 1991 dissolution of the Soviet Union. The term "cold" is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars.
