A Russian victory would end the global order, says Yuval Noah Harari

The Ukraine war remains the most important geopolitical conflict in the world, says bestselling author and historian Yuval Noah Harari.

In a wide-ranging conversation with Ian Bremmer filmed live at the 92nd Street Y in New York City, Harari says that if Russia wins in Ukraine, the global order as we’ve known it for decades is over. "The most fundamental rule was that you cannot just invade and conquer another country just because you're stronger. This is exactly what Putin is trying to do in Ukraine."

The conversation also touches on the potential ripple effects of Russia's actions, suggesting that a successful annexation could embolden other nations to follow suit, destabilizing global peace. Harari even entertains the notion that we might be in the early stages of a third World War, unrecognized in the current moment, much like the early years of World War II were not immediately identified as such. "If he gets away with it, we'll see more and more Putins all over the world” Harari says. "There is a scenario that we are already living in the midst of the third World War and we just don't know it."
