has Biden done a good job as president?

Nuclear Armageddon almost certainly will not be sufficient to kill humans as a specie.   But it will likely retard civilization for some time.   A full on nuclear exchange at the peak of Cold War probably would have set the entire human civilization back a century or two and permanently and dramatically change the character of human civilization.    An exchange between US and Russia now will mainly set back each of these two countries several decades. But still collateral physical, to say nothing of political and economic effects, will still be felt by almost everyone in the world.

None of these will end the human specie, but does warrant notice even if you live by yourself in a remote location, no matter how ghetto, third world, or “shit hole” the owners of these nuclear weapons have become.

As to us still being here,   Under Reagan, the world can to within 15 minutes from full on nuclear exchange a with near peak Cold War arsenal, when the Soviet Union almost launched on warning at false sign of american first strike, which came after they have been spooked by Able Archer, a pressure tactic under the guise of an exercise launched by the Reagan administration that realistically simulated mobilization, preparation for nuclear war, and deployment of nuclear weapon.

So one should be worried how cavalierly cowboy the US of A can be with responsibility for humanity.

Oh yes. One would be right into some kind of Mad Max future dystopia. It would not be pleasant for the survivors. Some here are old enough to remember how close we got to that kettle of insanity. It was a low level Russian military radar operator that saved the planet. An unsung hero.

Actually, it was the duty officer at the soviet early waning center.   His refusal to order launch of soviet counterstrike as per procedure is Arguable the single most impactful act of moral courage in all of human history.

His reward was a reprimand on his service record for not following procedure to properly document his actions as he made them.    As a result he was passed over for further promotions, and thus effectively drummed out of the service.
