Nuclear Realisation

Introduction
Small changes can make a big difference. For Albert Einstein, changing his mind about his support for the United States "Manhattan_Project" ruined his life. Regretting ever supporting such a monster of a weapon, he was prepared to do anything to stop it. The result being a terror campaign by Albert Einstein against the Nuclear program delaying it by years, and his execution for Treason in 1942. His death marks a martyrdom and creates a new ideology: "Militant Pacifism". Further afield, the Soviet Union and Imperial Japan are strengthened, and their cultural spheres impact modern society.

Point of Divergence
The PoD in this time line is the "Einstein-Szilárd" letter, sent on August 2nd 1939. Rather than continuing to support the Nuclear project in order to hurry its production, Einstein changes his mind and decides to write the letter attempting to stop the project. Obviously, the United States Government refused.

Einstein's Annoyance
Einstein took offence to the complete disregard to his opinions, and after several letters (the later turning into angry accusations and slurs) Einstein gives up, and tries to forget about it. A few weeks later, he still cannot sit idle, and decides on a plan of action. Using his status, friends, and some apology he is able to get access to some of the project's development. He uses this time to stage a bomb attack, to eliminate the evidence of the project and hopefully prevent it from being restarted. He is later helped by a group of people who realise what he is doing, and the group creates the underground organisation of Greenpeace.

The Attack and Aftermath
Einstein and his followers plan their attacks on several US research and military bases being used for the project's development, and time the co-ordination of all the bombs on the opening of the Office of Scientific Research and Development in December 1941. The attacks were a success, and halted the project's advancement; albeit with the deaths of dozens of military personnel, scientists and researchers. While Einstein and his group were efficient in planning their attacks, making an escape wasn't as successful. Einstein and many others were caught quickly, and a raid on a Greenpeace safe house in February 1942 was more than enough to convict them all for treason. They were quickly convicted and sentenced to hang for treason, which was carried out on the 16th of May 1942. The actions of Einstein destroyed any chance of the Nuclear bomb being used in the Second World War, resulting in its continuation until Imperial Japan's eventual surrender in February 11th 1947.
