NYU Law professor Samuel Estreicher defends Israel’s right to self-defense against Hamas, arguing that its actions in Gaza comply with international humanitarian law, particularly the principles of military necessity, distinction, and proportionality. Professor Estreicher refutes claims that Israel is an “occupying power” in Gaza and that the right of self-defense does not apply to non-state actors like Hamas, comparing Israel’s military actions to those of the U.S. against al-Qaeda and ISIS.

In this three-part series of columns, Illinois Law professor Lesley M. Wexler comments on the recent news that the Biden administration will be providing cluster munitions to Ukraine.

Amherst professor Austin Sarat argues that the Biden administration should join the rest of the world in officially opposing the death penalty by supporting the U.N. General Assembly’s resolution establishing a moratorium on executions. Professor Sarat points out that while supporting the resolution would not force the federal or state governments to change the status quo, it would put this country on record as committed to ending the death penalty—a particularly important accomplishment for a President who ran as an abolitionist.
