Fox News host Tucker Carlson offered a warning on Monday about the repercussions of removing Russian President Vladimir Putin from power, and suggested that Islamic extremists would somehow get hold of the country’s nuclear weapons and use them on Americans.

“So, Russia has a large and restive population of Islamic extremists. Do we think it’s possible that with no one running the country ― because of course we have no chosen successor to Putin ― is it possible, if we did that, that one of those 6,000 nuclear weapons might wind up in the hands of some anti-American terror group and be used against our civilian population here?” he asked. “A nuclear weapon! Well, it’s not just possible, it’s likely.”
