Previously, when looking at the real underlying national interests responsible for the deteriorating situation in Syria, which eventually may and/or will devolve into all out war with hundreds of thousands killed, we made it very clear that it was always and only about the gas, or gas pipelines to be exact, and specifically those involving the tiny but uber-wealthy state of Qatar.
Needless to say, the official spin on events has no mention of this ulterior motive, and the popular, propaganda machine, especially from those powers supporting the Syrian "rebels" which include Israel, the US and the Arabian states tries to generate public and democratic support by portraying Assad as a brutal, chemical weapons-using dictator, in line with the tried and true script used once already in Iraq.
On the other hand, there is Russia (and to a lesser extent China: for China's strategic interests in mid-east pipelines, read here), which has been portrayed as the main supporter of the "evil" Assad regime, and thus eager to preserve the status quo without a military intervention
