Meh, there are a whole lot of other things.
- Tactical bombers are a big problem; they have a range of 1500-2200km and you just can't get out of their range and stay out of the Arctic Circle.
- The Great Lakes present a lot of opportunities for fuckery. It's about 8000 km of US shoreline.
- What happens to the 60K US service members in the 100-200 US bases in Europe? Good question!
