"The West won't contain communism. It will transcend communism," 49th U.S. President Ronald Reagan said.

The papers say the U.S. had plans to target "population" cities, including Beijing, Moscow, Leningrad, East Berlin and Warsaw.
The National Security Archive writes, "Purposefully targeting civilian populations as such directly conflicted with the international norms of the day, which prohibited attacks on people per se (as opposed to military installations with civilians nearby)." (Video via U.S. National Archives)
The U.S. supposedly wanted to focus on destroying Russia's air power, which appeared to be the biggest threat to the U.S. and its allies.
"The event of nuclear weapons changed the course of the world as well as the war. Since that time, all mankind has been struggling to escape from the darkening prospect of mass destruction on earth," John F. Kennedy said.
Moreso, the papers say the U.S. wanted to drop bombs "ranging from 1.7 to 9 megatons" on these air power targets. There were also plans to develop a 60-megaton weapon.
As the National Security Archive explains, "One megaton would be 70 times the explosive yield of the bomb that destroyed Hiroshima." (Video via U.S. National Archives)
