Gideon Rachman talks to Jack Watling, author of ‘Statecraft: The New Rules of Power in a Divided World’

I think the US will go through a staged approach. So they will begin by attacking the anti-ship cruise missile sites, the bases where boats are kept, known launch sites for drones and essentially try and write down all the things that could attack ships there. Then they will need to start convoying, so having naval vessels go with the ships that are trying to get through in order to shoot down drones and missiles and other things that are fired at them. And the intent will be to get to a situation where there is a steady flow of shipping through the strait and the Iranians have accumulated enough damage that they’re not able to interdict."
