It sure is about time: Columbia University is finally starting to deal with the vile, antisemitic hooligans on its campus.

What took so long?

The Ivy League school is set to discipline more than 70 pro-Palestinian students for rampaging through Butler Library in May and for their involvement in last year’s encampment.

Most face suspensions of one to three years, and some will be permanently expelled.

The punishments are well-deserved: Students in the library were cramming for final exams last May. The tuition money they forked over gave them the right to use that library and the rest of Columbia’s facilities.

What right did the Keffiyeh Klan have to deny these kids what they paid for?

Their antics last year were even more selfish and outrageous.

They set up tents, preventing others from using public campus space, took over an academic building and harassed Jews.

“To create a thriving academic community, there must be respect for each other and the institution’s fundamental work, policies and rules,” a Columbia spokesperson said. Hear, hear!

The agitators should be grateful their punishments are only suspensions and expulsions: Last year, cops arrested some of them after they took over Hamilton Hall, yet bleeding-heart Manhattan District Attorney Alvin Bragg dropped the charges against most of them.

Columbia’s action comes after the school announced other small steps to curb campus Jew-hatred. It plans to hire more staff to investigate discrimination cases, for example, and will no longer meet with a virulent anti-Israel student group behind most of the chaos.

It also plans new antisemitism training for students and staff.

Most notably, it’s adopting a broader definition of “antisemitism” that aligns with what the International Holocaust Remembrance Alliance uses.

That includes expressing “hatred toward Jews,” whether physically or rhetorically, slurring Israel as racist and opposing the right of Jews to have a state of their own, Holocaust denial and justifying the “killing or harming” of Jews based on “radical ideology.”

These are certainly moves in the right direction. But there’s no excuse for waiting until now to act: Vicious antisemitism exploded almost instantly after Hamas’ Oct. 7, 2023, massacre of innocent Israelis.

That was almost two years ago.

Indeed, not until after Team Trump pulled $400 million of federal funds did Columbia even start to think about taking meaningful measures to right the ship.

And don’t celebrate the new moves too much, either. The school’s got a long way to go to cleanse its record of tolerating — even promoting — antisemitism.

Remember: Its armies of anti-American, anti-West, anti-Israel, Jew-hating professors remain entrenched.

They’ll continue to decry “settler-colonialism” and “apartheid” and brainwash impressionable young minds.

And it’s resisted other steps, too, like enforcing a mask ban on students for students who wear them to escape accountability and terrorize others.

Most of all, it’s still run by an arrogant, hostile board and an acting president, Claire Shipman, who’s tarnished by a putrid record — including statements that pooh-poohed campus Jew-hatred and sought to replace a Jewish trustee with someone who’s Middle Eastern or Arabic descent.

Columbia clearly has its work cut out for it.

Let’s hope its latest moves are just the first of many more.
