The anti-Israel activists at Columbia have really stepped up their vandalism game. Usually they are content to spray paint a few buildings or overturn some furniture. This week they have escalated to pouring cement into all the toilets in a building which could result in thousands of dollars in damage that takes significant time to repair. They posted video of themselves on Instagram along with a lengthy description of their actions.

We attacked two targets at Columbia University. First, the Kravis Columbia School of Business, one of Columbia's most recent violent gentrification projects into Harlem, the construction of which was conditioned on the creation of Columbia's Apartheid Global Center in "Tel Aviv". We will not allow this land-grab to go unchallenged. Second, we attacked the School of International and Public Affairs - the first Columbia institution to expel a student for their support for Palestinian liberation, currently run by a former "Israeli intelligence officer" - Killer Keren, and staffed by Rebecca Weiner, head of the Counterterrorism Unit of the NYPD, who directed the brutal police assault on our comrades in Hind's Hall last May. We left Hind's call painted on SIPA, and we cemented the sewage lines of the entire building, forcing them to shut down business-as-usual.

We are not experts in what it means to take revolutionary action. We are people - just like you - who, today, chose to act. We were afraid- to be arrested, suspended, and expelled; and that is exactly the point. The goal is not to be fearless, but to recognize that to be afraid is merely a symptom of our moral clarity. We are soberly aware of what we may lose if we act, and we are soberly aware of how much more we will lose if we don't. The most severe consequence we could face today is not expulsion or prison time- it is the knowledge that we had the opportunity to act, and, instead, chose cowardice.

They really are convinced that dumping cement in toilets makes them heroes. Embedding seems to be turned off for the clip but you can view it here or in the tweet below.

This wasn't just one or two toilets. They made a real effort to destroy the plumbing throughout the building.

The women’s restrooms on the fourth, sixth, 14th, and 15th floors of the IAB were “vandalized with a cement-like substance causing the toilets to clog,” Dean Keren Yarhi-Milo wrote in a Wednesday night email to the School of International and Public Affairs community...

The graffiti has been removed and Facilities staff “will be working throughout the night” to restore the plumbing in the building, according to the email.

Columbia has condemned the actions and says it is investigating with the help of law enforcement to identify the individuals responsible.

On Wednesday afternoon, restroom facilities at the School of International and Public Affairs were vandalized with graffiti that included disturbing, personal attacks. We immediately notified law enforcement, and an investigation was launched to identify the individual perpetrators and address their actions. Acts of vandalism of University buildings and property and attempts to harass and intimidate members of our community are unacceptable and abhorrent and will not be tolerated at Columbia. Our buildings and our classrooms are spaces for teaching and learning and we cannot permit them to be disrupted and defaced.  We are acting swiftly to address this misconduct and will update the community as we have more information.

This idea to destroy the plumbing with cement didn't just occur to them. Apparently it was spread during a training the group held earlier off campus.

🚨BREAKING NEWS: @ColumbiaBDS’s vandalism was premeditated.

As we watched yesterday’s footage of CUAD defacing @Columbia_Biz and pouring cement down toilets @ColumbiaSIPA, @Alon_S_Levin and had deja vu.

We’d seen this before—at Hind’s House.

CUAD concluded a teach-in… pic.twitter.com/RNNjj6cRJ2

The Free Beacon has more on how this was promoted months ago.

Columbia's student radicals met within the walls of a recognized student organization to train each other on all things anarchy. Included among the suggested readings was a manual written for "aspiring revolutionaries" that outlined the sewage cementing and graffiti soaking tactics used on Wednesday. And the student organization that played host appears to be in good standing with the school.

The apparently premeditated nature of the attack suggests Columbia could have impeded it by cracking down on the event's attendees and its host, Alpha Delta Phi (ADP), a literary society.

The ADP house was dubbed Columbia's "Museum of Terror" by the Free Press. Here's the sort of training they've been holding there.

In exclusive videos obtained by The Free Press, footage shows the first day of the Hind’s House exhibition. Nerdeen Kiswani, co-founder and leader of pro-Palestinian activist group Within Our Lifetime, is seen giving a speech to about 120 people, most of them wearing keffiyehs. Kiswani thanks the group for its takeover of Hamilton Hall and for “inspiring people all over the country and all over the world to take action.” She credits them for creating a space like Hind’s House so people can meet, organize, and “take over the city block by block.”...

“As long as Israel exists, it’s a genocide against the Palestinian people. Get to know your neighbors, get to know your community. . . and educate them. Provide them with resources, provide them with support if they’re attacked, but also demand that they take a side. A Zionist-free NYC is the only way that we can ensure that our universities don’t have the power to kick us out and silence us and to continue to fund Israeli genocide on our watch.”

Shortly after Kiswani spoke, three students took the stage to recite a poem with text “borrowed from the will of Yahya Sinwar”—the Hamas leader who masterminded October 7 and was killed on October 16, 2024, during a strike in Rafah. In their performance, students said they aspired to “inhabit the voice of Yahya.” After they concluded, the audience broke into applause.

This happened a couple months ago but Columbia apparently has done nothing while this group of extremists continues to escalate. At present they are content with disrupting classes, vandalizing buildings and destroying plumbing. But these wannabe terrorists aspire to more. How long before they decide to embrace violence against civilians just like their hero Yahya Sinwar did? Is Columbia going to wait until that happens before it takes this seriously?

Columbia did suspend one student who disrupted a class and two more have been identified and referred for discipline. The school is also discussing a mask ban and the possibility of bringing the NYPD on campus.

There's a saying that when someone tells you who they are believe them. These pro-terrorist students are telling Columbia who they are. Columbia should believe them.

A student at @Columbia (who just got back from her suspension for leading the pro-terrorist riots on campus) openly shares Hamas propaganda.

If this isn’t support for terrorism, I don’t know what is.

Is Columbia waiting for her to pick up an AK-47 or strap on a explosive belt? pic.twitter.com/X1ejnGYI2X
