But bob, what Gates did behind that big desk is make decisions like the one under discussion here.<quoted text>
Interesting as those comments were, Gate's who I have much respect for, sits behind a big desk in Washington.
IINM, at least one of the 4 victims was with Special Forces which had a number of men a couple miles from the "facility" in Benghazi.
He was ordered not to go try and help Stevens, but went anyway and lost his life.
How many other SF members were ready & willing to go, I don't know.
And I'm sure everyone including Gates knows the US has high-tech aircraft and weapons capability, easily able to avoid any POSSIBLE SAM missile strikes.
As far as a SAM-proof aircraft, well, that's news to me, particularly if you're asking the aircraft to fly low enough to effectively scatter terrorists surrounding/attacking a building.
