How the heck did this happen:

Not long ago, President Bashar al-Assad of Syria seemed a remote and embattled figure, with the United States threatening airstrikes and other Arab leaders denouncing him for having used chemical weapons against his own people.

Yet in recent days, he appears, paradoxically, to have turned the crisis to his advantage, making clear to a global television audience that he aims to use President Obama’s own “red line” against him.

For the answer, go back and read that Krauthammer piece in the previous post.
