I listed the four reasons above by which arms can be withheld. Violations of human rights and obstructing aid are not on that list, like it or not. I find it highly more likely that if there was any wrongdoing, it was Israel concealing the truth from US investigators, not bad faith of the US government. Biden was literally one of the drafters of United Nations Convention Against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment. I don’t see him standing by and letting that happen if he can help it.
