Either alive or dead, he will never leave.Saddam didn't, Qadaffi didn't, and Assad will follow them. So make quick work of him and get on with building a new free country! Russia (if it had a soul) should be ashamed of itself for supporting such a monster. The Arab nations will remember that Putin supported Assad as tens of thousands of civilians were slaughtered. When Russia's Muslims rise up, their call to arms will be 'Remember Syria!' He had better change his tune very quickly.
President Assad, for the good of your the country, (not YOUR country), flee for your life. You have overstayed your (and your father's) welcome.
