Lord Ricketts: US-Israel have 'no answer' to Iran's response to Khamenei death

Iran has dragged the world into an unsustainable war where '$1million air defence missiles shoot down $1,000 drones', a leading military expert claimed today.Lord Ricketts said the Iranians were running an 'asymmetric attack' on Gulf oil sites and the Strait of Hormuz because they have no match for US and Israeli airpower.The former national security adviser told how the 'curve of the war is still upwards' and he cannot see a de-escalation towards a ceasefire after the attacks on Saturday.It comes as Sir Keir Starmer will face questions in the Commons over his decisions on the conflict, after Donald Trump unleashed fresh criticism of the Prime Minister.The President said Sir Keir was 'not Winston Churchill' in a new rebuke after the UK did not allow US planes to launch their initial strikes against Tehran from British bases.
