The Bolshevik Revolution turned 100 last October. As Friday’s indictment of Russia’s Internet Research Agency reminds us, it’s been 100 years of tyrannical and murderous Russian regimes working to subvert democracy wherever they can and distort American public opinion by any means they can devise.

For decades, even in the post-Soviet era, the left wing of American politics laughed off this threat. It was not until Nov. 8, 2016, that it decided that Russia posed a serious threat to this country. This damascene conversion to faith in a new Red Scare helps them cling to conspiracy theories about President Trump colluding with Russian President Vladimir Putin to take over the U.S. government.
