Former U.S. Ambassador to NATO Kurt Volker has cautioned European nations against publicly criticizing President Trump's military operations involving Iran, warning of potential diplomatic consequences.

Speaking on Friday's episode of Politico's "EU Confidential" podcast, Volker advised European allies to exercise restraint in their public statements regarding U.S. actions. "You might think that this is a huge folly and going to have terrible consequences, but you don't have to say it," Volker stated during the interview.

The comments come amid ongoing tensions between the United States and European NATO allies over various policy matters. Volker's remarks suggest concerns about the potential impact of European criticism on transatlantic relations and alliance cohesion.

Volker served as U.S. Ambassador to NATO from 2008 to 2009 and later worked as Special Representative for Ukraine Negotiations under the Trump administration. His current comments reflect broader discussions about diplomatic coordination between the U.S. and its European partners on Middle East policy.

The warning highlights the delicate balance European nations must navigate between maintaining alliance solidarity and expressing independent foreign policy positions, particularly regarding military actions in sensitive regions like the Middle East.
