 Oppenheimer is history. Nuclear weapons were not. On top of waiting big at the box office, Christopher Nolan's Oppenheimer gave us a look into our past. But the work started by Robert Oppenheimer didn't stop in the 1940s. Instead, it set off a chain reaction. Today, nine countries have 13,000 nuclear weapons, a number expected to rise for the first time in decades. Experts say if just 100 Hiroshima-sized bombs were detonated, it would impact all of humanity. Soot from firestorms would dim the sun, causing crop failure and widespread famine. Yeah, I know, heavy stuff. But we don't have to live under the shadow of nuclear weapons, and most of us want a world without them. During the Cold War, people joined forces for peace, and we eliminated 80% of global nuclear arsenals. We can do it again by speaking up for policies and leaders that safeguard a future for all of us. Oppenheimer warned us against an arms race like the one happening right now. But it doesn't have to be this way. Together, we can make nukes history.
