It doesn't matter who won or lost (though the U.S. won i.e. 1815 Battle of New Orleans -- British took a thumping), you asked mre to provide examples of when America challenged a stronger, more powerful foe -- and I gave them to you.
Wrong. It was still a powerful Old World empire.
America had no reason to get involved in WW1 -- a war caused by Britain's intricate alliance system that was set into motion when a Serbian terrorist killed the heir to the Austrian throne. America did ultimately get involved when Wilson realized his view of an enlightened world word marked by liberalism, democracy, and capitalism could not exist in a world dominated by imperial Germany in addition to Germany's unrestricted submarine warfare.
Again, the U.S. had no reason to get involved in the European theatre other than it did not want to see Europe fall to Nazi Germany. A similar circumstance to WW1.
Britain capitulated like a 12 year old girl.
The U.S. wasn't defeated. We just decided that it wasn't worth it financially or militarily to continue to fight and thus, we pulled out. It's not like the U.S. was out of money, ammo, and troops and could no longer fight causing a surrender. U.S. politicians decided that the war was no longer worth fighting. You're right saying we didn't set out to achieve what we wanted, but it wasn't the military's fault -- it was the politicians fault.
Completely different scenarios.
