Not quite. We pushed thru the UN security council resolution telling Syria to withdraw from Lebanon. Granted, it's the UN, but it was something. In addition, Bush has put all tyrants on notice with his speeches, beginning two years ago in Whitehall England.
This is true.. but until the people showed some effort after the assassination, I don't the USA was as open as we are now. I think Bush is looking for any excuse to tightening up things over there. Syria has a chance to do the right thing. It's not a good situation for Assad, and he's too weak of a person to stand up to the goons around him. But now is the time for him to take action.
