"That's why you wage war as the last resort, not the first. You would think history major GW would have known that."
You should never fight a war unless you have the collective capability and will to see it through to victory. Otherwise, you're just allowing people to die (on both sides) for no real reason.
"We dropped more bombs on Vietnam than in all of WWII, including the big one(s)."
The difference is that the bombs being dropped in WWII were directed at enemy centers of gravity. The vast majority of bombs dropped in Vietnam were dropped on open jungle. The US killed a lot of monkeys, but monkeys weren't doing much to support the North's war effort.
And when the US finally did go after the NV CoGs, the results were devastating. The Linebacker II raids in 1972 put the North on the ropes. Had the raids continued into 1973, the North would have had little ability to defend itself or support it's proxies in the south.
"Americans fought far superior forces in the Revolutionary War using the same basic style of warfare that the Viet Cong and most of the other wars which we could never completely win because winning is impossible when we invade another country where we are unpopular with the people who live there."
The revolutionary war??? Jesus. Look at Afghanistan. The first Mujahedeen units that fought the Soviets were using the same rifles their great grandparents had used against the Brits. When an enemy is that committed, you really only have two choices. Leave them alone, or wipe them off the face of the planet. The Japanese were more than willing to sacrifice their entire civilization in the defense of the Emperor...up to the point where it became clear that A) they couldn't defend the Emperor, and B) the sacrifice of Japan was going to have virtually no impact at all on the adversary they were fighting. Their country was going to be burned to the ground by bombers who would be dropping with immunity.
