I dun see how it would benefit US to enter Libya, if i was in charge i would stay away. This mission just attracts more islamist militants against the "west" . Now the arab league seem to be withdrawing their support too.
1st of all, I am not pro western intervention but this situation is not balck and white
What is the alternative? What would happen without intervention? Gaddaffi will retake Bengazhi, many people will me massacred -fighter as well as civilians. And then situation will be back to normal for Libya.
The question is , is it acceptable to let Gaddaffi execute that plan?
