Just for the record... Kerry did volunteer to join the Navy. The rest of the story is this: John Kerry was drafted into the Army and did everything he could to get out of it.
He tried to get a college exemption (like Clinton got), but unlike Clinton, Kerry wasn't accepted to the college in France he said he was attending and the draft board declined his request.
Yep, he tried to get a one year exemption from the Selective Service( Draft Board), and was denied. He then volunteered in the Navy Reserves, hoping he could avoid any time in Vietnam.
During the draft if you wanted to avoid service in the Army you could enlist in another service, which was why Kerry joined the Navy (not a bad idea to be a sailor in the middle of a ground war.)
I'll be honest about it, I was drafted by the US Army in 1966, I was attending Albany State University, taking Computer Sciences courses; I didn't think it was the best thing for me to do( enter the Army), so before they got their mitts on me, I volunteered in the US Air Force instead. I never did see Vietnam - Alaska, Korea, Germany - yes.
He didn't volunteer out of a sense of service, he took the best of two bad situations for him.
