Russia is likely to veto the "western" UN draft resolution on Syria as it does not reflect the situation on the ground and is obviously an instrument to impose regime change if needed by war.
Unlike the draft resolution the report by the Arab League observer mission clearly tells of (pdf) brutal rebel attacks on the government and on civilian:
In Homs, Idlib and Hama, the Observer Mission witnessed acts of violence being committed against Government forces and civilians that resulted in several deaths and injuries. Examples of those acts include the bombing of a civilian bus, killing eight persons and injuring others, including women and children, and the bombing of a train carrying diesel oil. In another incident in Homs, a police bus was blown up, killing two police officers. A fuel pipeline and some small bridges were also bombed.
Any state will rightly use force to put down such armed gangs.
The Turkish president Gül is pressing for a fast solution:
“We regret this, but Syria is unfortunately on a path of no return. The important thing is that this process is not dragged out. There is no [good] end for this. The end is certain. The question is how painful it will be,” the president also said.
I see no fast way for the "west" to achieve regime change in Syria. A "no-fly zone" against a country where there are no military flights against the rebels makes little sense and a coalition of the willing is unlikely to evolve soon as everyone, the Turks, the Gulf dictatorships and the U.S., involved has a different idea of what the end game should be.
Despite ten month of attacks the Syrian state institutions and its military have held together well and there is no sign of any breakup. Without any serious forces on the ground any intervention just from the air would be insufficient. Who would be willing to declare war on Syria and to send their own ground troops? Turkey is the candidate with the most potential to do this but the risk of resistance to it in its own minority areas seems too high.
With the UN way blocked and an open war unlikely the U.S. and its followers will try different ways to get Syria under their control. Most likely they will increase in the weapon flow to the rebels and intensify their training of more rebel groups in Turkey and Jordan. The Saudis and Qatar will continue to finance their Salafi gangs on the ground.
This conflict then will continue for quite some time but with the Syrian government now seemingly more aware and able to counter the rebels.
Slowly but deliberately Assad is moving Syria's political system towards a more democratic state. That is probably something the "west" would really fear. A democratic Syria not under its control and therefor likely to continue its rather independent policies. This may explain the current rush to find a way to smash it before this happens.
