Princeton and NYU Professor Emeritus Stephen F. Cohen is increasingly alarmed that as Washington and Moscow drift toward military conflict, the US political-media establishment remains obsessed with “Russiagate”—allegations that Russian President Putin ordered the hacking of the Democratic National Committee in 2016 to abet Donald Trump’s presidential campaign and that Trump’s associates, possibly the new president himself, “colluded” in this “hijacking of American democracy.” No actual evidence has ever been made public regarding either the purported hacking or the collusion.
