President Donald Trump and North Korean leader Kim Jong Un met this week for a second summit, with some speculating in advance that an official end to the Korean War might have been one outcome (it wasn’t, at least not yet.) For many Americans, some who weren’t even alive during U.S. involvement in the conflict, the Korean War seemed to end on Feb. 28, 1983, the day when 121.6 million viewers watched the final episode of the TV show “M*A*S*H,” making it the most watched television broadcast in American history.
