We have and we have had this for a long time. I was born a few months after the Cuban Missile Crisis began. Nuclear threat has gone on throughout my life. Personally? I'm more concerned that Germany is re-arming when the Berlin Wall only came down in 1989. Accelerated devolution.
Both Russia and United States have over 1 thousand high-alert, launch-ready nuclear warheads.
I hope we never see a world war again. We will not survive it.
Stop this war. Humanity depends on it.
