Will Trump put boots on the ground in Iran?

As thousands of US soldiers and marines arrive in the Middle East, Iran is accusing Washington of privately plotting a ground assault while publicly touting ceasefire talks. Donald Trump threatened to ‘obliterate’ Iran’s energy infrastructure, said his ‘preference would be to take the oil’ in Iran and that US forces could seize the regime’s export hub on Kharg Island, while also claiming he was in talks with a new ‘reasonable regime’. Meanwhile, Yemen’s Houthi forces have also entered the conflict, bringing the threat of further damage to the global economy.Lucy Hough speaks to the Guardian columnist and host of Politics Weekly America, Jonathan Freedland
