Question

What was at the core of the Anti-Vietnam Movement?

Answer 1

To exactly which Anti-Vietnam Movement do you refer. You want a short answer. Simply listing the various groups would be too long, and each had its own ideologies. Guess it's time to hit the books. 

Feisty is right. I checked too. Since you only want short answers and no detail, it is abundantly clear that you don't want any reliable or relevant information. Good attitude. Lots of luck in life, but please to the rest of us a favor: when you're old enough, please, please, please DON'T vote.
