Fault line Syria: Russia and America both in the air, both bombing, but hardly talking as the battle temperature rises.
In what appears to be a new high watermark in the devastating conflict in Syria: Russia is no longer simply aiding Syria into the air and onto the battlefield but now joining the fight for herself. America some how discombobulated about what to do. Their own pilots having to avoid hitting the Russians whilst they accuse Moscow of hitting rebel forces that the US itself has trained.
We devote much of this programme to trying to understand what is happening in Syria and the implications for the rest of the world.
