The life of every terrestrial organism is being threatened with the steadily growing possibility of nuclear war because after the fall of the USSR a few imperialists decided that US unipolar hegemony needs to be maintained at all cost. I'm growing a uniquely deep hatred for people who scoff at me for saying that nuclear war is a real risk. There's no basis whatsoever for the belief that what the US empire is doing with Russia and China is safe. Your source is your own cognitive dissonance with the subject.
