Let's try that war from 1812 again.
How would you get the French to fight in the USA? Never gonna happen.
HAHAHAHAHAHAHA! I love you, Anna!
Well, Anna. There are French soldiers assigned to the UN Blue Berets, (A multi national contingent of the United Nations Peace Keepers). Of course, the UN would want to wait until the dust settled, before they sent the Blue Berets in. I suppose the next wave of international peace keepers would be the Chinese wanting their money back. And the list goes on.
