Libya 2011 is looking more like the 1991 uprising in Iraq by the day, at least from a US perspective. Except the US doesn't have half a million ground troops near Libya, and with respect to the Iraqi uprising it took the US 17 months (after the uprising started) to enforce a no-fly zone in southern Iraq: "In August 1992 the NFZ in the south to the 32nd parallel was established..." Between the beginning of the uprising (March 1991) and the establishment of the no-fly zone in the south (August 1992), Saddam's regime had murdered at least 300,000 Iraqis.
Will the US get involved militarily in Libya, other than to enforce a no-fly zone? Would the US send ground troops, or even special forces? What if Qaddafi crushes the rebellion, like Saddam did? Would the US allow him to stay in power for another 12 years, like Saddam did?
