The US has suspended talks with Russia regarding Syria. This is hardly surprising, but if bilateral talks are over, if Russia is supporting the Asad regime, and if the US wants Asad gone does this mean that hostilities between Russia and the US will increase? Given that Russia has stopped adhering to a bilateral nuclear disarmament deal (see previous post) it seems that we have our answer.
