Last November, in response to an ongoing wave of attacks, the Israeli defense ministry announced that it was considering deporting terrorists, possibly along with their families, from the West Bank to the Gaza Strip. Is this an effective deterrent? Contrasting the example of the 415 Hamas and Islamic Jihad operatives whom Israel expelled to Lebanon in 1992 with other cases, Adam Hoffman suggests that the evidence is mixed:

Israel deported [these] activists from the West Bank and the Gaza Strip in trucks to southern Lebanon, but Lebanon refused to accept them into its territory. As a result, they settled in a tent camp in Marj al-Zohour, [which] was controlled by Hizballah. The Shiite organization welcomed the deportees with open arms and [saw] an opportunity to forge connections with the Palestinian terrorist organizations. . . .

Hizballah trained the deportees, supplied them with food and equipment, taught them new fighting tactics, and upgraded their terrorism capabilities. It also taught [them] how to make the explosives and car bombs needed for suicide attacks—a terrorist tactic that was hitherto unique to Hizballah among Middle East terrorist organizations but that became a strategic weapon for Hamas after the Oslo Accords were signed. . . .

Before the deportation to Lebanon, Hamas, [as a Sunni organization], was averse to connections with Shiite Iran. However, according to Sakr Abu Fakher, a Lebanese researcher specializing in Palestinian politics, . . . the “psychological taboo against Shiism was broken in Marj al-Zohour, where the Palestinians came into close contact with Hizballah.” . . .

Despite the negative effects of deportation in these two cases, however, not every act of deportation necessarily leads to ideological extremism or to the improvement of terrorist capabilities among those deported. For example, most of the members of al-Aqsa Martyrs Brigade who barricaded themselves in the Church of the Nativity in 2002 and were deported to European countries and the Gaza Strip did not return to terrorist activity. . . . It appears that the effect of the deportation of terrorists depends mainly on the nature of the regime and the degree of governance in the country to which the terrorists are expelled.

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.
