I know, it won't happen because each community wants to keep the federal dollars flowing into their own neighborhood. Far more important than national security.
Just as President Bush fought for and won the authority to hire, fire, promote, and demote federal employees as part of homeland security, he can close down, open up, rearrange, etc., military establishments. Yes, it'll take plenty of maneuvering.
Meanwhile, troops can be stationed on the borders, training, drilling, partying, and securing the borders.
Bush may be reluctant to do this for fear of alienating the hispanic vote.
