In the weeks leading up to a potential military campaign against Iran, discussions within the White House Situation Room revealed how President Donald Trump's instincts and a tight-knit group of advisers shaped the path to war. Israeli Prime Minister Benjamin Netanyahu presented a compelling case for regime change in Iran, suggesting that the country was vulnerable and that a swift victory was possible. Trump's initial enthusiasm for the proposal was tempered by US intelligence assessments, which found significant flaws in the plan, particularly the unrealistic expectation of a popular uprising. Vice President JD Vance emerged as the most vocal opponent, cautioning against the potential for regional instability and economic repercussions. However, he ultimately agreed to support the decision if it proceeded. Many officials expressed private concerns but refrained from directly challenging Trump, allowing his position to solidify. Trump's confidence in achieving a quick victory influenced his dismissal of warnings about escalation and disruptions in key areas like the Strait of Hormuz. Ultimately, the decision-making process was characterized more by Trump's instincts than by consensus among his advisers.
