Before yesterday, when the President of the United States drew a red line, the World understood that it was crossed at great peril to the transgressor. Yesterday, the World understood that the United States of America did not make ideal threats. Yesterday, the World was safer.
The difference was created when the President argued that a military strike against Syria is the right thing to do and that he has the legal authority to do so. At the same time, he said he is going to ask Congress for approval.
Mr. President, more than seeking Congressional approval you need to look around the basement of the White House for boxes from the Truman administration and pull out that sign that says “The Buck Stops Here.”
