Yeah, they kept coming by the millions, and we kept killing them by the millions. The only problem was we decimated the population of Vietnam in the first two years. After that it was Chinese Regulars we were fighing, just like now it is Syria and Iran and Palestine we are fighting.
Before Vietnam, China talked about the Human Wave attack overwhelming us easily, After Vietnam they talked ping pong. Did Vietnam win? Sheesh, it never was about Vietnam. We kicked China's arse up around their necks in Vietnam till they learned their lesson and went home. Some victory, we won every battle and left.
Now the Jihadi are learning the same lesson. That is, if they are smart enough. It is very important that we do not just wipe them out with a few bombs, we must beat them face to face, over and over till they realize they if cannot win a war on even terms, how the heck can they win a war on OUR terms? After a enough time pounding their heads on the wall, eventually even a Muslim can figure out that Allah is not delivering victory to the "great Jihad fighters". They are getting stomped over and over and over every single time they dare to stand and fight men.
We must demoralize them, not depopulate them to stop a Jihad. We can always depopulate them at will if we ever decide that they just are too stupid to learn.
Islam is a cancer, Mecca is the tumor, radiation is a cure.
I hope we don't have a repeat.
