Why is no one pushing for a ceasefire, a separation of combatants, and a UN Green Line?
The international community and both sides in the conflict have actually pushed for a ceasefire, albeit sporadically. ISTR that an initiative to get both sides to the table was rejected by the rebels.
A green line...where? There are pockets of fighting all around the country. Where would you draw this squiggly green line?
While Russia will stand up to the USA, indeed it is probably only supporting Assad because the USA is supporting the rebels
Partly incorrect. Syria and Russia have been allies for some time, mostly due to the fact it is one of it's major arms importers in the region. I agree though that it is partly to do with Russian anger at the USA and the West for our actions over the last few years and Putin probably thinks enough is enough. It doesn't bode well though and I agree that the next few days/weeks could make for interesting times.
