The United States has had a neutral stance towards the ongoing conflict in Europe. However, the diplomatic relations have gone better with Great Britain and France than those with Germany and the rest of the Central powers. Yeah, yeah, yeah. Boring stuff, right? The Lusitania is sunk with over 100 American citizens on board, so in order to avenge this atrocity, Congress demands we go to war. Despite winning the 1916 election on the stance of "he kept us out of war", Woodrow Wilson brings the US into the conflict on this day in 1917. The Spanish-American war of 1898 proved we could push around the antiquated armies of Europe. The presence of our army in Europe tipped the stalemate that was ongoing and Germany was humiliated. But a couple of lessons were learned here. If the US wants to stick its nose into anyone's business, there isn't a hell of a lot anyone is going to do about it. See WWII, Korea, Vietnam, Iraq, Afghanistan, Cuba, Berlin, Panama, Libya, Bosnia, and Waco. Mess with the best, die like the rest.
