Well, as my girlfriend was saying, we are pretty strategically placed, (bodies of water/air control).
When you have that, and all your military expertise, i.e.
anti aircraft, Coast Guard, marines, etc, I think we have all our bases covered.
Of course, that doesn't help us for the enemies on the inside.
Anyway, something else I found interesting is that at the same time we're bombing Iraq, there have been squads of 1,000 soldiers raiding villages, doing random searches for Osama bin Laden, but of course, not in Iraq.
