By votes of 15-2 and 16-1, the ICJ has found plausible the charges of Israeli genocide that South Africa brought and that US Secretary of State Blinken said were meritless. The Biden administration has called on Israel to follow international humanitarian law but has continued to send military aid to Israel when it has carried out what the ICJ finds plausibly to have been genocidal acts. What should we do and what are we likely to do? We should admit that we have been complicit in supporting what the court finds to be plausible. We should switch the billions of aid that we have been giving to Israel to Gaza to enable Gaza’s right of self-defense and for its reconstruction. What are we likely to do? I rather expect we will largely ignore the court’s finding, reject it as political posturing, belittle this UN institution as having been captured by the majorities of nations, and veto any of the UN Security Council’s attempts to enforce it. If we do the latter, the Biden administration’s legacy will be the undermining of the international humanitarian law tradition that we had supported since the Civil War era Lieber code, the Hague Conventions of 1899 and 1907, and the WWII era Geneva conventions.
