What did Joseph McCarthy do?
In 1950 anti-communist hysteria began to emerge in the USA as
encouraged by the actions of Senator Joe McCarthy who began
accusing high-ranking US officials of being communists or at least
selling them secrets. Many government employees were found guilty
about passing on secrets about the Atom Bomb but he eventually lost
popularity and then soon power as his accusations grew wilder and
cruder each day. All this simply served to increase tension between
the two superpowers due to the hysteria created and the detest
shown by this senator towards the communists.
