"Hamas’ attack demonstrated, Rashid said, that the Axis of Resistance could destroy the Israeli state by launching surprise attacks from Lebanon, the Gaza Strip, and the West Bank simultaneously"
the risk is , of course, that if there are simultaneous attacks Israel goes for Iran and cuts off the problem at the root. A badly damaged Iran wouldn't remove Hamas etc but it would stop them very quickly. There are enough people in the countries they operate in who would be very very happy to take advantage of weakened Iranian support to "correct" one or two long running issues locally, especially in Lebanon.
