He’s been President-for-Life for 14 years and clearly intends to never leave the actual head of power in Russia. He’s been helping Iran acquire nuclear weapons; he’s been helping Assad stay in power. He’s been doing his best to shutdown US access to support our forces in Afghanistan through the “stans.” He’s done as much as he can to harm Israel. All that says more about his seriousness than his smiling or not smiling.
Assad staying in power is a good thing, since he’s protecting Christians in Syria from being slaughtered by the Muzzie Brotherhood... even though the Democrats and the GOPe wants the Muzzie Brotherhood in power instead.
