Danger of world war

I have been unlucky lately, as if death were nearing in the next few days, but I have not known why. But today I looked at the news in the internet and there was about danger of war between USA and Iran, but the picture of the text was dark: all black wiht just some soruce of light, like a danger world war. What can one do to prevent a world war, a nuclear war? Ordinary life for the last decades has been without war, especially without world war, so ordinary life is one option that one can follow. But of course some things like fighting, misfortyunes and too strongly said opinoons may be dangerous, likewise malicioursness. I have some texts which might help something in this:
