We haven't seen this kind of witch-hunting since the 1950s. The hysteria over the alleged "Russian threat to our democracy" has become the rallying cry of the Democratic Party and its Republican enablers. Eager to blame Hillary Clinton's defeat on anything but the fact that she was a bad candidate, what passes for today's "liberals" are blaming Vladimir Putin. They want to set up a new version of the House Un-American Activities Committee to "investigate" "Russian influence" in American politics.

This is a dangerous development: it augurs political repression here at home and a head-on collision with nuclear-armed Russia abroad. Some of us remember not only Joe McCarthy but also the Cuban missile crisis – when we came within a hair's breadth of a nuclear conflagration.
