ehh i'm inclined to disagree. It's the U.S. tanker (kc 10- kc135) assets flying orbits around the Med gasing up the strike fighters patroling the no fly zone. some of the fighters (like the F-15e) that crashed in libya are American, some are french/nato.
In addition i'm sure the navy is devoting some of their resources into the operation. The U.S. also has very specialized assets that would be used in this type of operation, ac-130's, ec-130's as well as various smaller aircraft like U-28, ea6b, predators, global hawks and logistical support etc..
Thats all in addition to the CIA and spec ops already "boots on the ground" in libya with the rebels.
don't let Obama fool you.
