“American history tries to make it sound like it was one-sided the other way – the Indians were all bad and the Americans were all-good.”
When you were a kid that was true. Not anymore. The Politically Correct storm troopers took over and school texts nowadays in American public schools tell you the white European guys were evil and victimized the poor righteous wholesome Indians.
“Same with the British. All the books make it sound like the Revolutionists were heroes. Hello, they were murderers.”
What are you saying about the British? And how were the Revolutionists murderers? The Torah recognizes the legitimate right of any nation to capture land from other nations via war.
