Unfortunately true, because Israel isn't going to carry out the sort of bombing that led to peace in Japan and Germany in 1945. They'll need to use lots of artillery and infantry as well.
Was just about to make the same point. The phrase “We can’t bomb our way to peace” sounds nice and catchy, but it is demonstrably untrue: we bombed our way out of WWII. And then made allies out of those we bombed.
