Ryan sat down with John Amble of the Modern War Institute to unpack the challenges Israel is likely to face in Gaza; Israel's world-renowned urban warfare training facilities; comparisons with other battles in cities such as those that took place in the Iraqi cities of Fallujah and Mosul; and how the initial Hamas attack overwhelmed Israel's preparations to defend itself. John and Ryan close by reflecting on how three Islamist militant groups have shocked the world and armies that were, on paper, better prepared than they were: the Taliban in Afghanistan, the Islamic State in Iraq, and now Hamas in Israel and Gaza.
