"Mccain told the Today Show:
The fact is that we could have ended this conflict a lot earlier if we had used the full weight of U.S. air power instead of leading from behind and we wouldnt have the 30,000 who are wounded and hundreds, if not thousands, who are killed.
Rubio told Fox News:
We have a lot of people dead and a lot of young men who, instead of entering the workforce and helping rebuild Libya, have to go into rehab and recovery for their war wounds. A lot of this could have been avoided had we gotten involved early and decisively.
And Graham told Fox News:
If we could have kept American air power in the fight it would have been over quicker. Sixty-thousand Libyans have been wounded, 3,000 maimed, 25,000 killed."
