That sounds cool...but Afghanistan and Vietnam were proxy wars, where the U.S. decided that holding onto a basket-case country was not worth the cost. And the actual military defeats occurred after the U.S. forces were gone.
American Revolution was not actually "Pilgrims against Britain", it was one of the western theaters in the Anglo-French(-Spanish) War.
Perhaps the U.S. pro-gun folks need to advertise more widely that their imagined "victory scenario" is "turn the U.S. into a smoking crater/basket case, which the U.S. Army won't think is worth holding onto"?
You'd give up your right to self defence to a government that would "turn the U.S. into a smoking crater" before they would return the power to the people?
Very few wars in history end with defeating every single last enemy, ie in WWII style. Most come to same conclusion - 'its not worth fighting anymore'. That requires sane leader of course, or deposition of insane one.
