NATO Secretary General Mark Rutte warned Sunday that Iran is “very close” to having the capability to strike Europe, citing growing concerns over Tehran’s advancing missile program.

Rutte’s remarks came amid reports that Iran launched intermediate-range ballistic missiles toward the joint U.S.-U.K. Naval Support Facility at Diego Garcia, though he declined to confirm the incident. He said the development underscores the urgency of efforts to degrade Iran’s missile and nuclear capabilities.

Drawing a comparison to North Korea, Rutte cautioned that prolonged negotiations could allow Iran to reach a point where its capabilities cannot be reversed. He said a nuclear-armed Iran, combined with advanced missile systems, would pose a direct threat not only to Israel and the Middle East, but also to Europe and global stability.

Rutte indicated that European leaders broadly recognize the risk, pointing to concerns that cities such as Berlin, Paris, and Rome could soon fall within range of Iranian missiles.

His comments come as the United States and allied nations work to coordinate a response to ongoing regional tensions, including efforts to secure the Strait of Hormuz. According to Rutte, 22 countries have joined discussions on how to address security needs and ensure the vital shipping route remains open.

Despite recent criticism from President Donald Trump, who has questioned NATO’s effectiveness, Rutte expressed confidence in the alliance, saying member nations continue to coordinate closely on defense and security challenges.

He also noted ongoing diplomatic efforts involving U.S. officials to manage broader geopolitical tensions, including the war in Ukraine, as allies seek to maintain pressure on Russia while addressing instability in the Middle East.
