The armed conflict in Gaza raises a series of questions under international law. The most significant questions concern the Israel’s use of force under jus ad bellum, the military operations conducted by the belligerents in relation to the law of armed conflict, and the proceedings brought before certain international courts, such as the International Criminal Court. This article examines each of these three issues in two stages. Firstly, it shows that the answers to these questions give rise to uncertain solutions insofar as they depend on the point of view adopted in relation to fundamental controversies concerning Palestine, such as the latter’s statehood. Secondly, it sets out the solutions that emerge independently of these controversies, whether these solutions express certainties or likelihoods.
