If you have the answers, maybe you should go to some of the VA hospitals and tell the Vietnam Vets why they were drafted into that war..
They were drafted into the war to defend liberty and freedom from the Communists. Then they were betrayed by the domestic Left whose loyalties laid with the enemy. Feel free to pass on the message... but I would guess they know already.
Why this country decided to afterwards put some of those same enemies (Clinton, Kerry, etc.) into high office is a question I cannot answer.
