Yes, we took the land from the British, the French, the Spanish, and more recently from the Russians, and made a kickass country out of it.
Edit: I see you Euros are still a little sore about us kicking your asses off our continent, but let's face it, you're so insufferable, its no wonder people here literally went to war so they wouldn't have to live under European rule.
This is what total war looks like. Make continuing the war so costly to the population that the other side gives up and won’t try again for generations.
This is the modern day equivalent to Sherman’s march to the sea in Georgia.
