The thing people today may not know about McCarthyism is that there WERE a lot of Soviet spies in the State Department. It desperately needed to be addressed.

The reason people forget this is because McCarthyism itself was not actually a very good remedy. It was great for the self-aggrandizement of Senator McCarthy (until he went too far, and his target Mr. Welch called him out while being interrogated before the Senate for making a national show of a very weak question of Welch’s colleague, a question could have been raised far more timely without the spectacle). It was great for building an atmosphere of fear, too. But in the end it was a pretty bad spy eradication program.
