1. Japanese attack on Pearl Harbor.
2. Germany and Italy declare war on USA 4 days later.
3. Extensive assistance given to the British by the US before the US formally entered World War Two. These aid programs and activities, like Lend Lease, supplied the British with desperately needed supplies, including oil, warships, weapons, food, and countless other items without which Great Britain might have been defeated by Germany before the US was able to overcome domestic resistance to getting involved in a European conflict. These aid programs were a violation of neutrality which the Germans ignored, not wanting the US to enter the war through subterfuge and misdirection, as it had in WW1. When Japan attacked Pearl Harbor, Germany was compelled by treaty obligations to declare war on the US, which in any case had been covertly engaging in limited hostilities against Germany for the previous two years.

The Progressive Era came to an end in 1917, which was the year the United States joined World War I. Woodrow Wilson was president from March 4, 1913 to March 4, 1921, including all of World War I.
The Americans, who came to the party very late in mid April 1917, joined the British, Canadians, Australians, New Zealanders, and the French. The American involvement was small and late. Jim Bunting. Toronto.
