Most analysts think Gaddafi has lost control of so much of Libya, that his downfall or demise is just a matter of time. I hope so.
The death toll is in the thousands, and those lives could have been saved if Gaddafi had done a Muburak. Of course the difference may just be that the Egyptian Army was less willing to kill it own citizens. To be fair most of the Libyan Army has been reluctant also.
A part of me sees some good from his decision to try and supress the pro-democracy movement by arms. Because it looks like he will fail, and will depart office (or life) reviled internationally.
This may prove a useful lesson to other dictatorships in the Middle East, and encourage them to peacefully engage with pro-democracy movements – not try and crush them.
