First of all, I didn’t set a red line. The world set a red line. So when I said that my calculus would be altered by chemical weapons, which the overall consensus of humanity says is wrong – that’s not something I just made up. I didn’t pluck it out of thin air. My credibility isn’t on the line. The international community’s credibility is on the line.
