Airstrikes on Libya

The airstrikes are more than just a no-fly zone, they've been targeting Qaddafi's mobile SAM's and armor, but less than a full scale invasion.

The problem with going half-way is that you do not eliminate Qaddafi's ability to attack. Qaddafi, instead of using overwhelming force via armor with a quick toppling of the rebel leadership and reasserting power, will now go door to door, inch by inch, foot by foot to reassert control of eastern Libya and the total casualties will be much higher than either:
1) not having airstrikes
2) wiping Qaddafi's forces off the map .

Also, have we not learned from Iraq that once you remove leadership in secular Middle Eastern countries, no matter how repressive, that Al Qaeda immediately fills the vacuum and it requires a long and painful groundwar to remove them?
