Following world war ii, the organization known as the north atlantic treaty organization was formed because anti-communist nations needed to show they were united. the ussr was threatening to occupy east germany. western european nations wanted to attack the ussr. western european nations were turning to communism.

The correct answer is the first one:the anti-communist nations wanted to show that they were united, to make sure they won't be attacked by the Soviet Union.
