This article analyses jus ad bellum questions arising from the 2006 war in Lebanon between Israel and Hizbollah. In particular, it examines Israel's claim to self-defence. Part 1 describes the scene of events and the actors. Part 2 explores whether the events of 12 July qualify, in themselves, as an armed attack. Part 3 concerns Hizbollah's and Lebanon's international responsibility for the attack. Part 4 examines whether Israel's actions complied with the legal requirements for a lawful act of self-defence.
