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.
Nothing terribly significant, the Dutch held quite a lot of territory around what is NYC, but they had long since packed up before the Revolutionary War.
I am sorry that kicking the Eurotrash invaders and their descendants off your continent didn't work out for you and in the end you were jammed into special reservations without being reimbursed for all the land theft after all.
