evidence: The Biden administration would be wise to adopt the more assertive stance against political violence set by the president on Saturday. Up to now, that has not been the case. For example, Haines and her colleagues went out of their way to note that, though the Iranians are clearly involved in the anti-Jewish violence that has become a staple of so much of American urban and collegiate life these past eight months, many of those participating in anti-Israeli demonstrations did so of their own accord, with nonviolent intentions, and without any knowledge of Iranian involvement. "I want to be clear that I know Americans who participate in protests are, in good faith, expressing their views on the conflict in Gaza," Haines said in her statement. "This intelligence does not indicate otherwise." [...] Survey the landscape of political violence in America, then, in the summer of 2024. We have a foreign enemy that has funded and organized campaigns that have resulted in violence against American citizens on American soil. We have an administration that acknowledges these attacks but needs to do more to stop them. We have local officials seeking to give the perpetrators a pass. And we have elite institutions that, while affected by the violence, rush to excuse it and to protect the worst offenders. President Biden is right to call out political violence. His administration acknowledges Iran’s role in provoking it. Now he needs to do something about it.
