The Iran war has sparked a significant backlash against former President Donald Trump from key figures within the Make America Great Again (MAGA) movement. Influential personalities such as Tucker Carlson and Megyn Kelly have openly criticized Trump's aggressive military rhetoric, labeling it as a departure from the 'America First' principle. Carlson referred to Trump's threats as 'vile' and urged resistance, while Kelly expressed her frustration with Trump's behavior. This internal conflict has been exacerbated by Trump's fluctuating stance on military action, oscillating between escalation and calls for ceasefire, which has alienated both hardliners and anti-war voices. Public opinion is shifting as a CNN poll indicates that support for military action has dropped from 41% to 34%, with disapproval rising to 66%. Even among MAGA supporters, opposition to a ground invasion has increased, highlighting a growing divide within the Republican base. The fallout from the Iran war is not just a domestic issue; it has strained Trump's relationships with right-wing leaders in Europe, who are distancing themselves from his military strategies. Experts warn that Trump's endorsement may now carry political risks, complicating his influence within the global right-wing landscape.
