After a certain point, desperate people aren't going to give a fuck about destroying themselves. They would prefer to die in triumph over their oppressors rather than drag out the inevitable and allow those oppressors to continue killing them slowly. We aren't at that point yet, but Trump's reign of chaos will very possibly push certain countries to the edge. This isn't even taking into account the existence of insane world leaders like Kim Jong Un, who couldn't care less about basic logic. We are all going to be roasted alive at some point, probably sooner than later.
