There's a civil war going on. Unless both sides cease and desist there would be no point. With regard to the chemical weapons he denies being the culprit.

You mean NEGOTIATE a settlement, those Syrians have live bullets and eat people, no self respecting politician is going to Syria to negotiate a peace deal! How would he get to his club for lunch, round to Dave & Sam's on Sunday for drinks or his hairdresser?

What if Assad said OK, what about the poor investors in the arms industry, they have to eat! No profit in peace you know!

Yes they tried to deceive him, but he refused !!

No.

But he has said he did not do it.
