Maybe it just seems like common sense to me, but if someone's on a terrorist watch and the CIA were objecting to allowing him citizenship, it probably wouldn't be wise to let him into the Army. But hey, its no-one elses fault that your government is stupid. :)
Also, that's four Muslims from the military who were indicted and/or charged by the US government. Out of an estimated population of 15,000 Muslims who serve in the US military. These were actual cases where people committed criminal acts, so of course there are probably a few more who harbour resentments toward the US. But that doesn't mean that you should kick them all out. If someone is an obvious threat (Ali A. Mohamed) then it is stupid to allow them into the military. But you shouldn't kick all Arabs/Muslims out because of the actions of a few.
