CNN has a long article and several videos under the headline Could Syria strike back if United States, allies, attack?

Here is one  video  that is an interview with Bilal Saab, an expert on the Middle East.

The interviewer does try to get Bilal Saab to consider more than he has considered up to that point in the interview, but she fails to get him to consider one obvious possibility. Whatever may be rational or irrational for Assad to do in response to our attack, if it were in fact the Syrian rebels that made the first attack, what is rational for them to do would be quite different from what it would be rational for Assad to do. What they had the ability to do would be quite different from what Assad could do.

The experts might be quite right that Assad would just shrug off the pin-prick attack planned by President Obama. However, while Assad was shrugging, the Syrian rebels might just mount an even bigger chemical attack and pin it on Assad again.

If the Obama administration is failing to take this possibility into account, then the President could be impeached for criminal negligence if this scenario actually plays out.
