And yes, I would close 90% (+/-) of our European bases leaving just enough ports of entry so the next time Europe F@@ks itself we have some bases of operations. I would give up Fulda Gap for that.
As far as a Cruise Missiles, they are limited range of about 500 miles. Ballistic Missiles are an issue. However, ICBMs are currently not mobile.
