US fears Iran ground war: Why 2.2 million troops are needed for Trump's regime change plan

• US 'Special Military Campaign' against Iran continues, with President Trump seeking regime change and a leader of his choice.
• Former Pentagon official Alia Awadallah states regime change requires ground troops, as airstrikes alone are insufficient.
• Iran's vast 1.65 million sq km area and complex topography would demand 1.5 to 2.2 million soldiers for occupation, far exceeding Vietnam War numbers.
• Mountain ranges like Zagros and Alborz, along with deserts like Dasht-e Kavir, pose extreme logistical and tactical challenges, making ground operations a 'death trap'.
• Experts warn that a ground invasion would be catastrophic for US forces, potentially burying America's superpower image if it fails.
