 I never forgave Truman for buckling under the pressure . He simply did not understand what it was about . As a matter of fact , after he stopped being President he still didn 't believe that the Russians had a bomb in 1949 . He said so . So for him to have alerted the world that we were going to make a hydrogen bomb at a time when we didn 't even know how to make one was one of the worst things he could have done . It shows the dangers of this sort of thing .
