O.K. So why has Assad kept quiet? Isn’t this a tacit admission of guilt after having been caught with his hands in the nuclear cookie jar? Usually the guilty are the only people who are compelled to silence.
Any noise he makes would draw attention to the fact that Syria is defenseless against Israel.
Have fun.
So he wouldn't feel pressured by his countrymen and fellow arabs to exact revenge and "do something" which he would then regret.
Since there are no editorials and commentaries in the arab press exhorting him to do something, he doesn't have to.
The question is "who died in the attack." There is a historic tradition in that area of using your enemies to take out your political rivals.
What if Assad put all his bad eggs in one basket...and then dropped the basket?
