On the sixth day of the US-Israeli war with Iran, the Strait of Hormuz is remains effectively closed to shipping, despite the US Navy crippling Iran’s surface fleet - including by torpedoing a Frigate off Sri Lanka. 

On today’s episode of Iran: the Latest, Roland Oliphant speaks to former Royal Navy commander Tom Sharpe about how Western militaries have prepared for years for a big war with Iran; why Iranian maritime forces are equally well prepared; and the cruel necessities of submarine warfare.

And Nicholas Hopton, a former British ambassador to Iran, explains the three conditions necessary for a regime collapse - and why none of them have yet been met.
