Which argument best supported the United States' involvement in World War I?

to show support for the US's strongest economic partners

to maintain the US's policies of isolationism and pacifism

to avoid the loss of American lives by getting involved in a war

to keep connections with the home countries of immigrants

to show support for the US's strongest economic partners

Explanation:

One of the main reasons the US got into WWI was its fiscal policy. Unfortunately, America turned from the world's biggest debtor to its biggest creditor. That may sound like a good thing, but what it ultimately meant was that we had strong economic ties to the Allied Powers, because if they lost they couldn't pay back our loans. I know. Sounds callous, but that's politics.

Why not B: Entering the war shattered these policies. Wilson's attempts at isolationism were put on hold when America entered WWI.

Why not C: This is the opposite: American lives were lost in WWI, of course, and our entering the war, however delayed, ensured that.

Why not D: This isn't relevant. Logically, politicians care little about cultural connections with countries of immigrants. They'll jump into the melting pot someday! (Right?)
