Developing the Hydrogen Bomb

Work on the Hydrogen Bomb began during the Manhattan Project, but not until the Soviet's exploded their first atomic bomb did efforts toward building the "Super" begin to take shape.

If we fight a war and win it with H-bombs, what history will remember is not the ideals we were fighting for but the methods we used to accomplish them. These methods will be compared to the warfare of Genghis Khan who ruthlessly killed every last inhabitant of Persia.
