The path to #HarryTruman's #AtomicDiplomacy (a nuclear threat to ensure compliance) winds through proposals like the #AchesonLilienthalReport, released on #ThisDayInHistory in 1946, and calling for a ban on #NuclearWeapons. The idea slowly withered under US and Soviet paranoia.

#HarryTruman's arrogant #AtomicDiplomacy pushed the Soviets to develop #nuclear power, and weapons, as quickly as possible. Their first self-sustaining reaction began #ThisDayInHistory in 1946 in the F-1 research reactor in #Moscow, which broke records by operating for 70 years.
