When the US and Israel launched their joint offensive on Iran more than a month ago, Tehran moved quickly to block the Strait of Hormuz.

Since then, the Revolutionary Guard has allowed some vessels to transit. But the majority, about 3,000, are stranded.

And Iran is accused of holding the global economy hostage.

On Thursday, the UK hosted a meeting of 40 countries to discuss the situation.

The gathering yielded no concrete results, except for an acknowledgement that further consultations were needed.

So, how should the Strait of Hormuz and other vital shipping routes be governed in times of war?
