After a year in which furious rhetoric has been pumped across Russian airwaves, anger toward the United States is at its worst since opinion polls began tracking it. From ordinary street vendors all the way up to the Kremlin, a wave of anti-U.S. bile has swept the country, surpassing any time since the Stalin era, observers say. 

The indignation peaked after the assassination of Kremlin critic Boris Nemtsov, as conspiracy theories started to swirl — just a few hours after he was killed — that his death was a CIA plot to discredit Russia. (On Sunday, Russia charged two men from Chechnya, and detained three others, in connection with Nemtsov's killing.)

There are drives to exchange Western-branded clothing for Russia's red, blue and white. Efforts to replace Coke with Russian-made soft drinks. Fury over U.S. sanctions. And a passionate, conspiracy-laden fascination with the methods that Washington is supposedly using to foment unrest in Ukraine and Russia.
