there isn't a single answer but here is a couple of reasons:
1)we intercepted a letter to Mexico from Germany trying to persuade Mexico to attack US and Germany would return TX and other land we took from Mexico.
2)we knew if Britain fell against Germany that they would come after us next
3)Germany attack unarmed US supply ships with their U-Boats and us civil non supply and non military boats
The Franco-Prussian War was not directly related to the entry of the US into World War I.
do you mean what caused us entry into world war one? if so then the sinking of the USS Lusitania by German u-boats was what caused American entry into the war
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.
it is bigg and strong and it had an influence to the countries
Militarism, the other three causes for US entry into the war are imperialism nationalism and alliances.
