Francois in Paris:

I've clearly stated that was no reason whatsoever to do it.

I never implied that you had.
I simply disagree that the war could have been won, independently of any reason for or commitment to the war.
WW2 ended with the surrender of Germany and Japan. The Vietcong as an organization couldn't be made to surrender. To win Vietnam the Vietcong would have had to be destroyed, because there really was no other political faction that had any popular support whatsoever. The Vietcong couldn't be destroyed without an invasion of the North. Said invasion probably would have brought nuclear armed China into the war.

Wait this is important. Someone is wrong on the Internet.
