Look at the effect nuclear weapons had on the world. There have been half a dozen near misses in total annihilation. The Russians got the technology almost immediately after it was created. We have lived in fear ever since. Rogue states, fear of nuclear terrorists. Now imagine the smart and capable people on the Manhattan project didn't push, didn't apply their brilliance. Simply said "the amount of uranium necessary to create a chain reaction is on the order of several tons, it is therefore not a viable weapon" and went on to work on more worthwhile creations. I argue the world would be a better place. Sure, maybe someone else would do it, but that person would be smart too and susceptible to the same sound argument. I'll say it again. We all have an ethical obligation not to build terrible weapons.
