The Russia-Armenia alliance is threatening Turkey, a critical U.S. ally
“The growing military alliance between Russia and Armenia is threatening Turkey, an indispensable U.S. ally and partner in the fight against the Islamic State."
Putin has a long memory and is no fan of Turkey's Erdogan. Conflict coming? Whatever Putin has planned I'd do it during the remainder of Obama's lame-duck presidency. I doubt if Obama would even lift a finger if Russia moved into Turkey.
