Last year, at colleges across America, students etched themselves into history, or infamy, with the most dramatic campus protests in a generation.

In preparation for the fall semester, some major universities—from NYU to UCLA—have implemented new rules and decided to enforce old ones to protect Jewish students from activists who had declared sections of campus no-go zones for Zionists. Universities that turn a blind eye to the Tentifada phenomenon now risk violating federal statute.

Nonetheless, the chaos appears to be returning. At Temple University, protesters marched in solidarity with Palestinian “resistance against their colonizers.” Last week, a man attacked a group of Jewish students with a glass bottle on the University of Pittsburgh campus outside the school’s “Cathedral of Learning.” Meanwhile at the University of Michigan, four agitators were arrested during a “die-in.”

So clearly the danger is not yet over entirely for campuses, even though some of the steam may be leaving the movement. The Democratic National Convention, for example, was supposed to be the exclamation mark of rage, but the protests barely registered as a tussle.

But history teaches us that it takes only a few student true believers to make quite a mess once they decide that boycotts and sit-ins aren’t making a difference.

To understand this moment and the risk these student protesters pose, Free Press columnist Eli Lake looks at America’s history with Ivy League domestic terrorists. More than 50 years ago, campus unrest also spilled into the streets and moved off the grid as a small and lethal group of radicals called the Weather Underground took the plunge from protest to resistance. But the Weather Underground railed against the establishment. Today’s campus protesters are supported by it. Call them. . . the Weather Overground.
