Alan Johnson and Calev Ben-Dor spoke to Michael Walzer, the leading American public intellectual and author of Just and Unjust Wars. We discussed the wars in Gaza and Lebanon, the charge of 'genocide' against Israel, the question of whether Israel is facilitating enough humanitarian aid to enter Gaza, as well as the pager attacks against Hezbollah operatives, and how Just War thinking applies to the conduct of war by a country in an existential battle against non-state actors.
