The conflict has raged for 2 years. Both China nad Russia has publicly stated that they would frown upon international intervention in what is essentially a civil war (i.e. arming 'rebels').
The latest news is that the West are not renewing the arms embargo to the rebels, and are actively looking to arm 'moderate' groups (bear in mind that their are a lot of extreme factions trying to get a share of the pie should the Assad Regime fall, some of which are more destestable than the present rulers).
Now Russia is arming the Assad regime (after previous reports of selling antiship missiles to them) to 'stabilise' the conflict.
What i can see from this conflict is that the 'East' (Russia/China) have a big stake in Syria (and/or the Assad Regime), policitically or economically, and do not want to see the situation get resolved.
The West as being pressured to resolve the situation mainly for political/geographical reasons (on the doorstep of Israel, a totalitarian Muslim Nation, etc.), and on the surface of it due to pressures to resolve the humanitarian disaster. The western powers tell their public that 'they want to help' but in the same breath say they wont intervene directly, hoping for another Libya (internal struggle that 'resolves itself'
The humanitarian considerations are completely a secondary. Where was NATO for the last two years? tens of thousands of civialians killed, millions displaced, this is totally a secondary consideration to the western world and not even a consideration to the East.
Unfortunately this conflict is a reflection of world politics today. People are more interested in their poll ratings and arms sales figures than the poor b*****ds dying in the street.
Obviously feel quite strongly about this, apologies if it's too strong for this forum.
