Hollywood celebrities are speaking out en masse against the military strikes initiated by the United States and Israel against Iran. On Saturday, Donald Trump took to Truth Social to announce the attacks, claiming that negotiations aimed at curbing Iran’s nuclear capabilities and preventing war had ultimately failed, necessitating military action. The reactions from some well-known figures have been swift and pretty intense. Jack White, former lead singer of The White Stripes, posted on Instagram, talking about Trump’s track record concerning international conflicts during his second term, while mocking the president’s appearance. He asked, “Don’t you love seeing him declare war on a country while wearing a trucker hat that says ‘USA’ on it?” View this post on Instagram White sarcastically labeled the president “the leader of the ‘Board of Peace’” and pointed out the perceived interchangeability of various countries like Venezuela, Greenland, Iran, and Cuba in the president’s foreign policy. White highlighted that it would be “other people’s children” who would have to fight, not Trump’s own. He also made a pretty sharp comment about Trump not receiving a “real Nobel Peace Prize yet,” calling it “Unfair!” His critique was just the start Longtime critic Rosie O’Donnell also joined the chorus on Instagram by highlighting quotes from Trump’s 2024 presidential campaign. One quote read, “If Kamala wins, only death and destruction await because she is the candidate of endless wars. I am the candidate of peace. I am peace.” The other stated, “I’m not going ot start a war, I’m going to stop wars.” O’Donnell simply captioned her post, “He lies only and always #impeachtrump.” Under Article I, Section 8 of the U.S. Constitution, only Congress has the power to declare war, as well as to raise and support armies, provide and maintain a navy, and fund and regulate the military.Impeach the SOB.— Stephen King (@StephenKing) February 28, 2026 Actor John Cusack shared his thoughts on X, suggesting that Trump’s decision to enter into conflict with Iran was a classic “wag the dog” move. He claimed it was a way “to distract from Epstein and to do Netanyahu‘s bidding – who’s lobbied for this for over 30 years.” He then added a pointed question, asking if we have “had enough yet.” View this post on Instagram Carrie Coon also posted her objections on X. She took a sarcastic jab at Trump’s recently formed international relations committee, writing, “’Department of War.’ They weren’t kidding about that.” We all know President Trump declaring war means America's brave men and women putting on uniforms. It’s moms, dads, and spouses holding their breath. It's the fate of the Iranian people hanging in the balance.Agree or not, pray for our troops and for the families who shoulder… https://t.co/brbUtWt8g0— Jillian Michaels (@JillianMichaels) February 28, 2026 Meanwhile, on Instagram Threads, Mark Ruffalo weighed in by posting an article about Jared Kushner, who served as one of Trump’s lead negotiators with Iran. Ruffalo’s caption was concise and impactful, stating, “He was sent to make sure we went to war.” View this post on Instagram The sheer volume of these public criticisms shows how deeply this military action has resonated within Hollywood. Their criticisms have also been echoed across the political space, with Marjorie Taylor Greene being one of the first voices to rebuke the President.
