Well,he's right there.Israel cannot fight a war of attrition.However,I wonder if they might have weapons that might allow Israel to win a quick war.My hunch is.....that they do.
They have between 500-800 nuclear weapons, some of them thermonuclear. Unlike Iran, some of Israel’s nuclear missiles are installed on submarines, where it would be nearly impossible for anyone to get to them, so they have a second strike option. Only the US, Russia, China and UK have bigger arsenals.
