A grim anniversary: 75 years since Hiroshima. Has the world learned the lessons from that attack? Well, it was the first and so far only time an atomic weapon was used; is this enough though?
Don't forget Nagasaki as well. Besides that, more than 500 atmospheric nuclear tests have been conducted up until the early nineties (+ about 1500 underground tests), releasing considerable amounts of radioactive materials into the environment, partially transferred into the oceans for the past decades. It caused the largest collective dose of radiation. Not sure if the health impact is known or if authorities want to know it. So from that point of view, we learned nothing...
Definitely not forgetting Nagasaki; that anniversary is on 9 August. And yes, of course, testing has gone on for decades.
At least we didn't blow ourselves up, that's that... ;) All those tests would have been enough to end us if launched on the same day... We should probably find a way to get rid of the nuclear stockpile but then how would deterrence work? Would we have even more conventional wars without the nuclear option?
