We speak to the president of NATO's Parliamentary Assembly, just hours after Israel launched major strikes on Iran's military and nuclear sites. Marcos Perestrello is a Portuguese politician and a former secretary of state for national defence in Portugal. He calls for "de-escalation" in the Middle East and more nuclear diplomacy, while also making the case that Iran is a threat to the region and to global security, and that the development of a nuclear programme in Iran would be "an even bigger threat to global security".
