The thing about Romney and national defense and foreign affairs, is that he has no personal interest in it, whatever he says, whether good or bad, is just something that his advisers issue for him.
His dad was laughed out of the presidential race of 1968 for claiming the military had “brainwashed” him on Vietnam, and while campaigning to be commander in Chief, Mitt was evading the draft and living in France with a deferment issued by Mormon headquarters (Mormonism at the time issued their own deferments to the draft board, but blacks were excluded from it by the Mormons).
Mitt actually left the GOP when Reagan took over.
