Going in would be a seriously bad idea. Help provide humanitarian sea and air lifts of refugees to other Arab countries - yes. The average guy may just want a way out of the craziness. Anything else - no.
If we send The Marines in there, the first thing that will happen is they will be attacked. Let the Libyans sort their own mess.
The anti-American muzz (and the vast majority in Libya are just that) don’t even deserve our humanitarian help let alone putting the lives of our troops at risk.
