On the 27th of September Israel dramatically escalated its war on Hezbollah, by assassinating its Secretary General Hassan Nasrallah. Four days later Iran responded to the killing of its long-standing ally by launching a missile attack on Israel - targeting military and intelligence facilities. In today's episode Eskandar Sadeghi-Boroujerdi and Nathaniel George join PTO to talk about whether the killing of Nasrallah - and the wider leadership - represents an existential threat to Hezbollah, and about the group's prospects in combating Israel's ground invasion. We also talked about the effectiveness of Iran's missile strikes and the degree to which Iran has been able to restore any measure of deterrence. We also touched on the dire humanitarian situation in Lebanon, which comes on top of years of grinding economic and political crisis. Finally, we discussed the position of the United States and the apparent appetite in Washington for settling accounts with the America's regional adversaries.
