From Kabul to Tehran: How US diplomacy turned transactional
US President Donald Trump has repeatedly criticised Nato allies for failing to support the US-Israeli attack on Iran on 28 February, an escalation that led to the closure of the Strait of Hormuz - the world’s most critical energy artery - bringing misery to millions across the globe.
