Yes, but we did have to fight the Indian wars to establish westward expansion. Also, many wars have been fought over ownership of lands—not with the inhabitants of said lands, but with other countries that want ownership of said land.

My main point is that all the lands on this earth have been “stolen” at some point, some many times, throughout history. If we’re going to dissolve the US based on this delusion that this country was “stolen” from the natives than every country better start working on returning their land to the prior people they “stole” it from.
