Don't you find it odd that they announced that? Almost like they wanted the terrorists to know that those planes were leaving...and that there would be less protection. (By the way, those were AWAC planes, not figihters. They were monitoring communications, I believe.)
Now why would Rumsfeld, who won't talk about anything that might risk his people, do that? Hmmm.
I will leave you to your own conclusions, but it helps to THINK a bit, before making a comment. Also, loose lips sink ships.
Intelligence gathered on Americans by foreigners can be freely shared with any American national or local law enforcement, a point which may now be moot with implementation of the misnomered Patriot Act.
