Over the past three years, Tehran has been exploiting the chaos in Iraq and Syria to expand its influence in the Levant, with an eye toward establishing at least one, and probably two, corridors under its control through which it can funnel weapons and troops. These corridors, writes Ehud Yaari, go from Iran, across both the Tigris and the Euphrates rivers, through the Iraqi desert, into Syria and then to Lebanon, much of which is under the control of Hizballah, itself a proxy of the Islamic Republic. The endpoint is Israel’s northern border (free registration required):

The ultimate purpose of the corridors . . . is to expand Iran’s reach into the Golan Heights, with the goal of tightening the noose around Israel. The Iranians publicly express their keen interest in opening up the Golan front to their proxies, and high-ranking Revolutionary Guard officers are engaged there now in the establishment of a new militia—the Golan Regiment—partly composed of Palestinians residing in Syria. Ahmed Jibril, the veteran leader of the Iranian-sponsored Popular Front for the Liberation of Palestine, has been advocating such a move in the Golan Heights, a call that has also been echoed at various times by the official Syrian media.

Such a tactic would extend the current frontline in Lebanon between Hizballah and Israel all the way down to the Yarmuk River, where the Syrian-Jordanian-Israeli borders meet. Leaders of some Iran-sponsored Iraqi militias . . . are already talking openly about their intention to move their forces to the Golan front. Israel has retaliated several times to attacks coming from that region, and one Iranian general was killed during those clashes.

In responding to Iran’s plan to secure influence in the Levant, the Trump administration should work with its regional counterparts to thwart Iran’s attempt to build these two corridors. Turkey, a NATO ally, should be encouraged to resist Iran’s efforts to dominate, through the corridors, the main trade routes [bearing] large amounts of Turkish exports to the Arab world. The Kurds, both in Iraq and in Syria, should be provided with military equipment to face the [Tehran-backed] Shiite militias. . . . The United States should back Israel’s effort to prevent the Iranians from securing a foothold on the Syrian side of the Golan Heights. But above all, the United States should continue talking with Russia and insist that sooner rather than later, the Syrian leader Bashar al-Assad will have to go.

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.
