Tom Nichols: “In the past week, the president of the United States has conclusively turned America into an ally of the Russian Federation.”“Donald Trump has now abandoned pretense and is openly aiding the Kremlin in its war against a friend and partner of the U.S. The American commander in chief has abandoned the Western order, the most successful—and powerful—security arrangement in human history.”“To judge from the available evidence, he has not done so out of a cold calculation of the national interest. Instead, he has based his decisions on his own interests; his open admiration for Russia’s dictator; his resentment of Ukraine’s democratically elected president; and quite possibly other factors that so far have remained obscured from the American public.”
