[quote] DEFENCE chiefs have warned the PM about a new Cold War with Russia after revealing the Kremlin has sent “tens of thousands” of troops to Syria. Moscow has been secretly building up military advisers and technical experts in the war-torn country, intelligence officials have learned. Many are manning tyrannical leader Bashar Assad’s Russian-made air defence systems. Their presence means David Cameron’s plan to arm Syrian rebels would lead to a direct confrontation with Russian leader Vladimir Putin. [/quote] Oh fun.
