The Franco-Prussian War was not directly related to the entry of the US into World War I.

Communist aggression.
I don't think the idea of freedom had much to do with the US entry into World War I or World War II. The US declared war on Germany in 1917 after the sinking of the Lusitania, where a number of US citizens died. The US entered World War II after the Japanese attack on the military bases at Pearl Harbor, Hawaii, and the German and Italian governments declared war on the US the next day.
The Japanese bombing of Pearl Harbor.
the entry of US troops.
