The Americans were upset over the Stamp Act because Great Britain imposed an internal tax on all paper documents in her colonies. If the Americans wanted anything printed, it had to be printed in the United Kingdom and there was a tax or levy imposed on the printed documents. The reason for the Stamp Act was that Great Britain was in debt after the Seven Years War, and she was looking to recoup her losses after the war. Needless to say, the Americans were very unhappy that they were being punished for the war.
The main reason why America's ties with the Allies were stronger than the ties with the Central Powers was because of economic reasons. The Allies purchased large amounts of weapons and war goods from the United States. Germany was developing its own weapons thus it didn't enlist for American supplies.
