If our enemies got a nuke, they could leverage its effects a thousand times by putting it on the Las Palmas Cararies volcano, where a chunk the size of Manhattan is perched precariousy.
If a nuke would dislodge it....that's all she wrote folks.
Except most tsunami experts have concluded a collapse of that volcano would do nothing to the East Coast of the US.
If they had a nuke I'm certain they wouldn't take the chance of wasting it there.
