i say stay out

The Libya situation is (thus far) a strictly internal affair. 

There is no direct threat to anybody outside of the country, and no undo influence from any other country on one side or the other of what is effectively a civil war.

If we get involved, oil prices will continue to rise.  If we DON'T get involved, oil prices will continue to rise.

Occam's Razor would therefore suggest staying the hell out is our best course of action.
