The Americans gives us a thought-provoking look at the behind-the-scenes machinations in both the United States and Russia on the day President Reagan was shot in “In Control.” Interestingly, both sides are concerned about the same thing: who shot the president and what does it mean for their country? If what is portrayed in this fourth episode has a modicum of truth to it, little did we know that World War III was narrowly averted thanks, in part, to the Russian spies living in America.
