Britain, and thus the US, should have stayed out of WWI and let the Kaiser have France.

WWI was a battle between colonial powers over colonial commerce and power. The US had no interest in that war. The WWI Germans were not the Nazis in any way.

WWII was different, but we should have let them fight WWI to their stalemate.

[Campion]

Britain entered the WWI because Germany invaded France through Belgium, and Britain had a treaty of alliance with Belgium to guarantee Belgian neutrality.

The US entered WWI because of German submarine attacks on American shipping, and especially because of the Zimmermann telegram.

In other words, both the US and Britain entered the war because of German misbehavior, not to save France. Saving France was just an unintended [cough] "benefit".
