The US was attacked.
Part of the cold war.
the main reason was the slavery rights
US citizens became tired of the war.
It is called the Mexican American war for a reason. The US fought Mexico.

The major reason for the US exchanging neutrality for the war of 1917 was that the Germans were using their ships to attack the Us ships. The US ships were carrying American citizens at that time.
