It was a false flag attack by rebels and the only one who supposedly benefitted from it was them. It's basic math and given the nature of animals in some opposition groups, it's the most logical scenario.
1) Victims of the attack were Assad enemies.
2) Attack was carried by large number of Volcano rockets. Only Assadists have them.
3) Azimuths measured by UN commission indicate that attack came from Assad positions.
Anyone more than 1 digit IQ realizes that it was carried by Assad.
Assad wouldn't gain anything by using gas, but rebels would gain a lot, like convincing the west to attack Syria, which they ultimately failed.
Assad had many benefits:
1) He killed over thousand of his opponents and their supporters.
2) Tens of thousands if not hundreds of thousands forced to flee.
3) He became a partner for international deal, boosting his legitimacy.
4) He showed to his opponents that he can do with them literally anything and no one will care. For example after chemical attack Assad launched starving campaign on Ghouta. No one cared. Several months later Assad launched absolutely insane barrel bombing of Aleppo and again no one cared.
5) #4 this led to desperation and sharp rise of Islamists among his opponents which again helped Assad to pose himself as "moderate" and boots international legitimacy.
What he lost from this attack? Absolutely nothing.
Are you afraid of election?
The current chaotic situation in Syria is the outcome of the very same people like you who have considered themselves as legitimate decision makers on behalf of Syrian people .. let them choose what they want for their own future and respect the outcome ....
Again, would u let Hitler run elections in 1945? There is no difference here.
Baath and SSNP should be prosecuted just like Nazism and banned for good (they ARE actually Nazis and dont even hide it). Leaders should be shot like mad dogs middle ranks sent to jail. After that u can make elections.
