Leftist Obsession with Russia is the New McCarthyism

At great piece, from Ted Galen Carpenter, at the National Interest, "Why Democrats Are Obsessed with Russia":

Progressives need to adopt a course correction. Those who sincerely believe their shrill rhetoric need to get a grip and not succumb to Russia Derangement Syndrome. Those who are cynically using the anti-Russia hysteria as a club with which to beat the Trump administration need to pause and consider how their actions are triggering a second “cold war” with the one power that has the military wherewithal to destroy America. In either case, their current behavior is doing their country a grave disservice.
