Don’t get me wrong, it’s great he wants to serve. But with the changes soon to be coming, one, do you really want to be under the command of Obama, do we trust he will use the military properly? Second, the gay issue could be a big one to deal with. Third, the personal health issue of the vaccines they are given. He could be taken out by the vaccines before he ever gets to serve, and he’s permanently disabled.
Perhaps if he is interested in service to the country, he could be a deputy, or firefighter, or go the FBI/CIA route if he’s interested in federal service.
The only one that is bad that they give now is the Anthrax vaccine (which was almost given to everybody after 9/11). All of the others are the same as if you were traveling to the region as a tourist.
