False accusations against which organization led to the demise of senator joseph mccarthy?
a. the u.s. army
b. the u.s. state department
c. the u.s. air force
d. the u.s. senate

The correct answer is A. the U.S. Army. In 1954, McCarthy accused officials in the U.S. army of communist sympathies. The hearings on the case were nationally televised, and many Americans soon began to realize how crazy and over the top Joseph McCarthy was.

D. they had very different political philosophies that lead to a deep mistrust of each other.

not only did their political philosophies differ, but also their economic systems. the soviet union was strongly socialist and the united states believed in capitalism. both hated one another and thought their side was the only way to run a successful country. what it came down to was that both countries were terrified of the other's ideologies being imposed on them. neither wanted to convert, for they felt it would be their downfall. it was a battle of ideologies.
