In a rare address to Russian citizens this week, President Wladimir Putin Make clear He would not shy away from using nuclear weapons to defend Russia. The news sparked a reaction Palantir Technologies Inc PLTR chairman alex karp, who previously issued a wake-up call for those sleeping on the threat of nuclear war.

What happened: In a May 24 interview on CNBC’s Squawk Box, Karp warned that we underestimate the risk of nuclear warfare.

“One of the reasons we underestimate risk is because we’ve had a system since World War II that works … and people believe that system will override itself and it will be rational, but we’re in now a moment when the system actually topples and there are just moments of complete irrationality,” Karp explained.

Why it matters: Russia’s invasion of Ukraine is an irrational act that increases the risk of escalation. The defense system has worked in the past, providing a sense of security, but Karp hinted that the world is far from safe.

“I think most people think about the risk [of nuclear war] is like below 1%, of course it depends on the duration. So if you have long duration, I think the risk is … probably in the 20% to 30% range,” he said.

Every major nation in the world reassesses its capabilities after the war between Russia and Ukraine, Karp said: “The lesson for every great country is holy shit!”

Nations will realize they are not as protected as they think, and if adversaries are willing to fight with determination and heroism and able to use software to interpret data, our enemies could “actually beat us.” said Karp.

“We are in very difficult times,” he said. “Palantir is built for difficult times.”
