Answer
Brief Explanations:
After World War II, the Soviet - Union's expansionist intentions in Eastern Europe made Western European countries fear for their security. NATO was formed as a collective - defense alliance to counter this perceived threat. The Soviet Union had not yet initiated damaging attacks on Western Europe at the time of NATO's formation. Reducing military forces and focusing on infrastructure rebuilding would not prompt Western European countries to join a military alliance. The Soviet Union's withdrawal from the UN Security Council was not related to Western European countries joining NATO.
Answer:
The Soviet Union had shown that it wanted to expand its area of control in Eastern Europe.
