Whatever little coalition or cabal came up with the idea of deposing the Assad regime needs to have their heads examined. They new full well that the man had chemical weapons. How in the hell did they expect to take Assad out and avoid the chemical weapons issue ? Did they think he would not use them in a last ditch effort to save his own life ?

No, I think you've got it backward, with respect.
Assad was WINNING. That's why I myself suspect it was a false flag operation, gassing rebel areas by rebels because they were desperate to provoke US intervention before they lost irrevocably and were all killed.
However, I could be wrong and Assad was simply cleaning up areas of resistance like Saddam did with the Kurds on his way to victory.
The point with chemical weapons is that they work best against villages, not troops.
They were invented to use against troops, but that worked very, very dubiously and only 4% of WWI battlefield casualties were caused by poison gas. The word "blowback" was of course invented in connection with poison gas.....you can see the potential problem.
