Very good points regarding the inevitable demise of the both the equipment currently used (MBT) and the notions of traditional maneuver warfare. Both the vehicles and the tactics are extremely expensive in terms of men, material, fuel (food for men, gas for vehicles), not to mention rallying the will of a nation to fight for anything less than it's very survival.
I also agree with 'Manstein's Revenge' regarding nuclear options. The "wars" that are coming our way now are for control of and/or access to resources and no nation is going to contaminate the regions thus denying themselves access to whatever the "goodie" may be.
If there were a release of nuclear weapons, I foresee it as a sabotage maneuver, done to deny the aggressor their prize. Let's face the truth, American forces are not needed to hold any large swath of land in the Arab or Persian countries, only the oil fields, production facilities, and the ports to load the outgoing tankers.
The countries that are blessed with desirable resources know "Western" countries will be friendly only as long as those resources are cheap, plentiful, and easily accessible. The day any one of those criteria are threatened, the term "regime change" becomes topic #1.
For this reason, unconventional is the way to go. Oil rich nations would be well advised to train their militaries in insurgent warfare and to simply purchase existing nuclear weapons from Russia or China and place them amongst the oil fields, thus assuring that any attempt to steal the resource by force would be met by denying safe access to the oil for several thousand years. The "Doomsday Device" idea put forth in 'Dr. Strangelove', as it were.
'Manstein's Revenge', on the subject you brought up about the B-25 being named for Billy Mitchell, to your knowledge, was this the first time the Americans actually "named" an aircraft? Weren't aircraft simply referred to by their type/model, (PBY, P-51, etc.) while the British actually named them (Catalynia, Mustang, etc.)?
