The most important area of cutting he mentions IMO is some of our overseas bases. Especially the ones in Western Europe. The Soviets aren’t coming through the Fulda Gap anytime soon. This was the whole basis for some of these huge bases during the cold war. Sure, we probably need to have airforce bases in some of these places so we can transport our personnel but our forward deployed overseas bases need to be concentrated in the Middle East and the Pacific. These are where our current threats are. We have these bases already. We need to close a lot of the ones in Western Europe.
You may be right. Those bases, however, are popular duty stations for troops (join the military and see the world), and that may be a consideration for decision makers. Also, cutting all the bases may make sense in the light of current threat, but what about future threat? They may turn out to be crucial. It's hard to negotiate the establishment of a new base when negotiating from the position of great need.
