Imagine if the American people elected a president who was much worse than George W. Bush or Barack Obama. A real tyrant. Would that be sufficient justification for someone like Vladimir Putin to arm and train Mexican and Canadian mercenaries to invade America, kill US civilians, destroy cities and critical infrastructure, seize vital oil refineries and pipeline corridors, behead government officials and prisoners they’d captured, declare their own independent state, and do everything in their power to overthrow the elected-government in Washington?
