NOT since before the beginning of the Cold War has a U.S. politician been as fervently pro-Russian as Republican presidential nominee Donald Trump. Just four years after his predecessor Mitt Romney declared Russia to be Washington’s greatest geopolitical threat, Trump has praised President Vladimir Putin as a real leader, “unlike what we have in this country.” Trump has also dismissed reports that Putin has murdered political enemies (“Our country does plenty of killing also,” he told MSNBC), suggested that he would “look into” recognizing Russia’s annexation of the Crimean peninsula and questioned whether the United States should defend NATO allies who don’t pay their way. When Russian hackers stole a cache of emails in July from the Democratic National Committee’s servers, as security analysts have shown, Trump called on “Russia, if you’re listening,” to hack some more.
