Earlier quoted context omitted.
You have a distinctly queer idea of what happens after a war. This isn't an American idea to take land after conquest, it's how it's always worked throughout human history, even with the Indians that warred amongst themselves prior to the American government becoming the ultimate victor against them. You may disagree with the foundations of the conflict, and you can argue on those merits if you choose, but the result…
I find it amusing that you hold a blanket thought that the theft of Native American land was the result of war games and not a mixture of deception, racism, genocide, breach of trust, and thievery.
Deception, killing, accepting/breaking agreements, and taking things is basically war in a nutshell. It is an extension of diplomacy. How you execute these parts is a matter of your goals, and your morals and ethics.
But it's not THEFT. There is no such thing as theft when it comes between two nation states, it's either yours or it's not yours, and how well you can defend it basically is the rule of the game.
If you deceive yourself enough to assume you aren't at war, while the other side sends you all the signals that they are at war with you, whose fault is it when you eventually fall?
You may hate it, but don't redefine something basic to the politics of humanity.
