Here are three suggestions for keeping our tankers safe from Iranian aggression when passing through the Strait of Hormuz;
Assemble tankers in convoys with RN warship escorts - timing dependent on tides, numbers. Extendable to include other threatened nations who can contribute warships.
Helo on a squad of Royal Marines with .50cal rail-mounted weapons, shoulder-launched missiles etc to each tanker making passage through danger zone, transfer them to tanker moving in opposite direction for the return leg

Elect Corbyn as PM so he can ask his Hamas and Revolutionary Guard chums to lay-off UK tankers in return for UK breaking sanctions against Iran
