Countries engage in proxy wars in order to:
a. push rival countries to drop out of long term arms race.
b. protect their weaker allies from potential destructive conflicts.
c. promote their interests without directly engaging with each other.
d. avoid interference from their countries’ military-industrial complexes.

While I agree with the explanation, I believe the answer is “C.” The US promoted its interests by supporting those countries threatened by Soviet expansion, never having to directly engage with the Soviets. This was part of the Truman Doctrine that sought to contain communism by supporting insurgent movements against the Soviets.

In my honest opinion , i’d say franklin d roosevelt was a president that impacted our nation , i say this because fdr is voted among top three best us presidents and he was the longest serving president by 3 terms , usually presidents only supposed to have two terms increments of 4 years , equivalent to 8 years total before election time. and he established the fdic , through the 1933 banking act and he established the us , social security system , during his presidency, and established a national minimum wage , through the fair labor standards act , fdr led the allied coalition to victory in wwii and he played a major role in the creation of the united nations.
