Syria has allegedly used chemical weapons against civilians once again. When Obama was president, he foolishly said that such use would be a ‘red line’. When chemical weapons were subsequently used, Obama’s bluff was called, and he effectively did nothing. The episode substantially weakened the US in the Middle East, and helped Russia ease its way back in, a proc ss that continued for the remainder of Obama’s term.
Trump hasn’t said anything quite as specific about chemical weapons, but he has talked tough, and he has sought to differentiate himself from Obama. If he does nothing in the face of th s outraged, it will be perceived as weakness. I expect he will order a strike on some Syrian government or military facility to send a message.
