Or an LNG tanker can be used as a bomb, or a crude oil supertanker rammed into a city on autopilot. The possibilities are limitless.
And there is not much we can do to stop it without severely hindering free world trade, leading to a global depression.
OTOH, look at the bright side. The arab death cult islemmings will be totally quarantined from world trade, and will have to find a way to drink oil and eat sand.
We will have a bad period of adjustment to the new economic realities, but the islemmings will starve by the millions, being totally dependent on outside food, with very shaky water resources. (A half dozen bombs could destroy 90% of Saudi Arabia's water desal plants, leading to the end of them once and for all.)
It's a classic case of nasty creeps living in a glass house throwing pebbles at the giant who owns the rock quarry. Long term, it's suicidal for them. Alive or dead, their oil will still be there waiting to be pumped by anyone who takes the fields.
