In a gaffe unthinkable for someone in a position as respected as the United States Presidency, Ronald Reagan jokes on a hot mic about bombing Russia on this day, August 11, in the year 1984. 

Unique to the men that filled the office before him, Reagan was a former actor, and was known for his clever way with words--but the “bombing Russia” joke was considered by many to be an embarrassing political gaffe, and not the first of his career, according to History.com

It is difficult to imagine a president being so careless with his words, but the president's flippant remarks would turn into an international embarrassment and provide much fodder for the Soviet propaganda mill
