Question

The NATO alliance represented a historic transformation in American foreign policy because a it committed the United States to a permanent peacetime alliance with other nations b it meant establishing military bases outside the territory of the continental United States c it departed from the principles of the Monroe Doctrine d it put the United States into the position of guaranteeing the permanent subordination of Germany

Answer 1

A

Step-by-step explanation:

The USA has always followed a principle of neutrality, this alliance marks the end of that. As the US is now in an alliance, it would have to involve itself to help defend its allies (and peace).

Also, being in an alliance doesn't necessarily mean establishing military bases. Furthermore, by this time in history, the US has already made military bases outside the border.

The Monroe Doctrine opposes European interference in the Western Hemisphere (Latin America), it has nothing to do with alliances.

Germany has nothing to do with the alliance either. Some of the allied leaders may want to do that, however, it is not officially part of the agreement.
