would they deploy UFO craft. -

I've been wondering if a big threat came upon the USA and lets just say USA has "ufos" do you think they would break the secret to survive?

No, if the existance of UFO's is fact then it a multi-generational cover up and the impact on previous administrations, General's and Politicians in the know would necesitate continued denial even under the most extreme circumstances.

Sure they would. What do you think the black triangles are for?

who the hell needs a UFO when you got long range nuclear missles?!?! We got the bombs baby!

As an MDIA special agent i will tell you that no area 51 similar bases DO NOT CONTAIN any type of UFOs, ET type beins in the U.S.A or any other country

I'm sure there have been several ideas tossed around in Washington, but not quite in the context of your question. I think their final recommendation is somewhere along these lines:

The NEXT time we stage an attack on the USA we should...

Use our remote controlled UFOs and stage an ET invasion...then we can try out our new P.L.A.A.S.M.A. (Particalized Laser Anti-American Spaceship Murdering Array) and crash them into the Halliburton, Raytheon, and Carlyle Group accounting buildings.
