The Manhattan Project put to debate the new technology of fission reaction in the last years of WWII. On one side, there was the opinion that the use of uranium could be helpful during the war, since the presence of an atomic explosion might dissuade Japan from surrender instead of making a full-scale invasion to the island. On the other side, there was the academic opinion that mentioned that nuclear energy might cause more frictions between nations. In my opinion, I think that the nuclear energy, derived from the Manhattan Project, used during WWII was needed to finish the war as soon as possible, however, that doesn´t justify the rise of the Cold War. Nowadays, that same source of energy (if handled properly) could provide an alternative source of power, instead of oil, to diminish contemporary climate issues.
