Last month, a scandal broke out when it became public knowledge that President Trump shared with the Russian foreign minister highly classified information—provided by Israel—about Islamic State’s plans to get bombs onto airplanes. The president was soon accused of jeopardizing Israeli and American intelligence operations against Islamic State (IS) by providing specifics about intelligence-gathering to an unfriendly nation.

What specifics in particular? Relying on information provided off-the-record by current and former U.S. officials, the New York Times undertook to disclose them. Israel, it reported, had been conducting an extremely sophisticated cyber-intelligence operation against IS that gave it access to detailed information about terror plots.

Now that this information has been published, writes Elliott Abrams, IS will surely be able to identify and guard against the “tool” that Israel is using to spy on its operations. Other countries, too, will likely be able to protect themselves against similar espionage, forcing Jerusalem to cease making use of a piece of software that likely took years to develop and could have otherwise yielded much more vital information.

It’s hard to tell how much damage was done, [by the president’s comments to his Russian guests], because he did not reveal how the information [about IS] was acquired. That task was left to the New York Times and to the American officials who leaked highly classified information to the Times. Those officials committed a crime. . . .

I don’t know whether the president’s disclosure infuriated Israelis, [as the Times reports], but I know that the Times’s unprincipled and irresponsible disclosure damaged not only Israel but our own safety. It helped IS. . . .

The officials who leaked to the Times leaked information of the highest sensitivity and classification, which is why I called it a crime. That leak, and the decision of the Times to print the story, endangers Israeli security and American security. To what end? What is achieved? . . .  [I]t’s just a small part of a campaign against Trump. And it seems advancing that cause, for the leakers and the newspaper, trumps our security and that of an ally.

While it is commendable that administrators of several universities finally called upon police to crack down on violent and disruptive anti-Israel protests, the actions they have taken may be insufficient. At Columbia, demonstrators reestablished their encampment on the main quad after it had been cleared by the police, and the university seems reluctant to use force again. The school also decided to hold classes remotely until the end of the semester. Such moves, whatever their merits, do nothing to fix the factors that allowed campuses to become hotbeds of pro-Hamas activism in the first place. The editors of National Review examine how things go to this point:

Since the 10/7 massacre, Columbia’s Jewish students have been forced to endure routine calls for their execution. It shouldn’t have taken the slaughter, rape, and brutalization of Israeli Jews to expose chants like “Globalize the intifada” and “Death to the Zionist state” as calls for violence, but the university refused to intervene on behalf of its besieged students. When an Israeli student was beaten with a stick outside Columbia’s library, it occasioned little soul-searching from faculty. Indeed, it served only as the impetus to establish an “Anti-Semitism Task Force,” which subsequently expressed “serious concerns” about the university’s commitment to enforcing its codes of conduct against anti-Semitic violators.

But little was done. Indeed, as late as last month the school served as host to speakers who praised the 10/7 attacks and even “hijacking airplanes” as “important tactics that the Palestinian resistance have engaged in.”

The school’s lackadaisical approach created a permission structure to menace and harass Jewish students, and that’s what happened. . . . Now is the time finally to do something about this kind of harassment and associated acts of trespass and disorder. Yale did the right thing when police cleared out an encampment [on Monday]. But Columbia remains a daily reminder of what happens when freaks and haters are allowed to impose their will on campus.
