Seventy-two minutes. That’s how long it could take from a country launching a nuclear weapon to global nuclear winter and the end of human civilization. 

If that’s not scary enough, the United States is right now involved in two proxy wars involving nuclear powers — one in Ukraine, and the other in the Middle East. 

Today on Lever Time, David Sirota asks acclaimed investigative journalist Annie Jacobsen, author of Nuclear War: A Scenario, the big bombshell questions: What scenarios are most likely to trigger a nuclear conflict? What can be done to pull us back from the brink? And just how close are we to the worst-case scenario?
