I didn’t watch President Obama’s address on Syria last night. I did this morning through the magic of Youtube. I seriously doubt that it changed anyone’s mind. I haven’t been able to locate an overnight tracking poll yet but I suspect that relatively few people saw the address, those who did learned nothing new, and they’ve already made up their minds.
A distinct question is whether President Obama helped his own approval rating with the address. Right now it’s hovering around the lowest level of his presidency. If he decides to attack Syria, it will be with the full recognition of that and in the knowledge that 2/3s of the American people disagree with him.
My opinion is what it has been for some time: that the U. S. should makes its case to the Security Council before taking any action, that the Congress should authorize the use of force before the president takes action, and that what control we have over events is limited to whether we attack Syria or not rather than over what happens afterwards.
I have hopes for Russian Foreign Minister Lavrov’s proposal for ending Syria’s chemical weapons use and, presumably, its program but on that we’ll need to wait and see the details as they emerge.
