Syria and Russia - NOT amateur radio

See http://www.bbc.co.uk/news/world-middle-east-35809087 .

I am no expert on Middle East politics but this move by Russia surprised us all. They still keep their bases in the region, but I think no-one (except maybe the US military?) was expecting this. Does it make peace in the country more (or less) possible? I only hope that all players work towards a peaceful and fair outcome for all in this war-torn land. The people of Syria have suffered too much.
