Vice President JD Vance warned European allies attending the security conference in Munich, Germany, against “the threat from within,” arguing that European governments are exercising extreme censorship and have failed to adequately get a handle on “out-of-control migration.”

“The threat that I worry the most about vis a vis Europe is not Russia, it’s not China, it’s not any other external actor,” he said Friday. “What I worry about is the threat from within, the retreat of Europe from some of its most fundamental values, values shared with the United States of America.”

Vance denounced Romania, a NATO ally, for its recent cancellation of presidential election results over evidence of Russian disinformation. “If your democracy can be destroyed with a few hundred thousand dollars of digital advertising from a foreign country, then it wasn’t very strong to begin with,” he said. “I’d ask my European friends to have some perspective.”

He also appeared to voice support for right-wing parties that have been banned from joining governments in Europe, saying, “Democracy rests on the sacred principle that the voice of the people matters. There’s no room for firewalls.”

Vance said of all the pressing challenges facing Europe and the U.S. “there is nothing more pressing than migration.”

He blamed the “series of conscious decisions made by politicians all over the continent and others across the world,” and he highlighted the Thursday attack in Munich where an Afghan national drove a car into a crowd, injuring at least 30 people.
