Bolstered by a momentous ICJ ruling, Palestinians, including Americans, gave three hours of testimony against the Biden administration.

Lawyers involved with the lawsuit playing out in federal court said that the ICJ ruling bolsters their case. Their lawsuit argues that Biden, Blinken, and Austin are liable under U.S. law for failing to uphold their obligation to prevent genocide in Gaza.

Barry Trachtenberg, a professor of Jewish history and author of two books about the Holocaust, testified as an expert witness in the case – over repeated objections from Justice Department attorneys. When he filed his declaration in the case in November, he said, some 11,000 Palestinians had been killed. Today, that number is far greater.

“Everything that we feared and more is unfolding,” he said, noting that often, legal actions about genocide happen long after the fact. “What makes this situation so unique is that we’re watching the genocide unfold as we speak. And we’re in this incredibly unique position where we can actually intervene to stop it using the mechanisms of international law that are available to us.”
