Is Hungarian Prime Minister Viktor Orbán undermining Europe and Western unity following this year’s critical NATO summit? Just days after Hungary’s nationalist leader met with Russian President Vladimir Putin in Moscow and Chinese President Xi Jinping in Beijing, Orbán left the NATO 75th anniversary summit in Washington, DC to visit former president Donald Trump, a well-known critic of the alliance, at his Mar-A-Lago estate.

On GZERO World, Ian Bremmer sat down with Polish Foreign Minister Radek Sikorski on the sidelines of the summit to ask how NATO members deal with a renegade ally like Hungary and the challenges posed by Orbán’s coziness with authoritarian rulers. Orbán’s rogue trips are a sharp contrast with NATO’s unified stance, on full display at the summit, but Sikorski insists Orbán doesn’t represent the EU or NATO.
