The length of Offut AFB is 4.3 sq miles, Vatican City is .17 sq miles (about .4123 x .4123 miles). You could fit 25 Vatican Cities on Offut. Offut is, I believe, a big base, but even so, any 'base' the size of the Vatican City would be fairly dinky.   Also, there is a shitload of installations in Iraq, not 'a base'.

I don't know what's going to happen. There are extremists on one side, rosy-visioned and trusting, that think everything's going to be peachy, and go completely according to plan, and there are extremists on the other side, paranoid and ..., well paranoid, that are sure the world will end, or we're doomed to spend eternity (or at least that part of it we're alive for) in Iraq. I think the sane thing would be to smoosh both sides together. I think the truth is not extreme, and I think people who are completely sure how things will go are mostly close-minded nuts. Me? I think it's quite possible Iraq will fall apart. I don't have any idea what our reaction will be.
