Republican Leaders Back Trump’s Iran Campaign Amid Clash with Pope Leo XIV
House Speaker Mike Johnson and Senate Republican leader Mitch McConnell have voiced strong support for President Donald Trump’s military actions against Iran, even as Trump escalates his rhetoric with threats to severely weaken the Islamic Republic.
McConnell, responding to questions about Trump’s online statements, affirmed his backing of the administration’s efforts. “They’ve been at war with us for 47 years,” the Kentucky senator said. “They’ve killed Americans. They’ve killed Israelis. They’ve killed throughout the Middle East. They’re bad guys.” McConnell acknowledged uncertainty about how the conflict would conclude but noted that Iran’s military capabilities have been “significantly diminished.”
The Trump administration’s strikes on Iranian targets, aimed at dismantling nuclear ambitions and terrorist infrastructure, have drawn sharp criticism from the first American pope, Leo XIV. In a Palm Sunday sermon, the pontiff declared that Jesus “does not listen to the prayers of those who wage war,” emphasizing a message of peace.
Speaker Johnson, a Southern Baptist, pushed back by invoking centuries-old Christian teachings on just war theory. Speaking to reporters Wednesday, he expressed surprise at the pope’s remarks and defended the theological grounding for the U.S. operation. “It’s a very well-settled matter of Christian theology,” Johnson said. “There’s a doctrine called the just war doctrine.”
Vice President JD Vance, a Catholic, also addressed the controversy at a Turning Point USA event. He highlighted the more than 1,000-year Christian tradition of just war theory, which weighs moral justifications for conflict. “If you’re going to opine on matters of theology, you’ve got to be careful,” Vance said. “You’ve got to make sure it’s anchored in the truth.”
Just war theory, rooted in the writings of Saint Augustine and later developed by Thomas Aquinas, holds that war can be morally permissible under strict conditions: legitimate authority, just cause (such as self-defense or protecting innocents), last resort, proportionality, and efforts to minimize civilian harm.
Johnson argued that the strikes align with these principles by neutralizing Iran, long considered the world’s leading state sponsor of terrorism. “The fact that you had the nation that was the largest sponsor of terrorism now having had that ability taken away from them… that means potentially millions of innocent people will be able to keep their lives,” he said. He added that while religious leaders are free to speak, entering political debates invites responses.
The Trump administration maintains that the campaign, which includes a U.S. Navy blockade of Iranian ports along the Strait of Hormuz, seeks to prevent Tehran from developing nuclear weapons and to force a diplomatic resolution. Trump has intensified his criticism of the pope on Truth Social, writing: “Will someone please tell Pope Leo that Iran has killed at least 42,000 innocent, completely unarmed protesters in the last two months, and that for Iran to have a Nuclear Bomb is absolutely unacceptable.”
The public exchange between the president and the pope underscores deep divisions over the morality and strategy of the Iran conflict. While Republican leaders emphasize national security and the protection of allies, the pontiff continues to call for restraint and dialogue to prevent further bloodshed in the region.
