I’ve watched Jewish friends ask “is it safe to check in here as a Jew” before booking hotels this year. Some called them paranoid.

Then you see this. A Jewish couple greeted with “baby killer” by an employee at a hotel reception in California.

Turns out it wasn’t paranoia.

32% of all office leases expire by 2028.

52.6% of Class A and 54.2% of Class B expiring space carry positive rent growth potential.

Except San Francisco. Both classes still showing negative spreads.

Raw data overstated the office downturn by nearly 3x.

But the quality-adjusted recovery is just as muted. Rents are only 7.8% above 2019 levels at year-end 2025.

Manhattan #office rents "surged" in 2022.

Except they didn't, and it was mostly trophy building leases skewing the average. The Columbia CompStak Rent Index strips out compositional bias. Check out the deep dive with @Columbia_Biz here: https://t.co/Oesot8ozPT

Everyone's talking about the Palantir effect. The #data tells a different story. 88% of South Florida's biggest office leases came from in-market companies, not new arrivals, according to CompStak.

The President of the United States addresses the nation about the Islamic Republic of Iran, flanked by the Easter Bunny.

We are living in a simulation.

[Ahmed Al-Khalidi @khalidi79397]

I envy the Israeli left.

Not their politics. Their freedom.

They march through Tel Aviv calling their own country an apartheid state. They go on CNN and call the IDF war criminals. They write op-eds in Haaretz comparing Israel to the worst regimes in history. They join NGOs funded by hostile governments to produce reports designed to delegitimize the Jewish state.

And then they go home. Sleep in their beds. Send their kids to school the next morning. No one threatens their family. No one disappears them in the night. No one drags them from their home.

Zero consequences.

Now imagine, just imagine, if Iranians had 1% of that freedom. If an Egyptian columnist could criticize Sisi the way Gideon Levy criticizes Netanyahu. If a Palestinian in Ramallah could call Abbas corrupt on live TV and walk home safely. If someone in Gaza could have held a sign saying "Hamas does not speak for me" without being executed.

The Middle East would be unrecognizable.

The great irony is that the people who enjoy more political freedom than virtually anyone else in the region use that freedom to paint Israel as a tyranny while the actual tyrannies they're silent about would imprison or kill them for doing the same.

You're not brave. You're spoiled. You mistake comfort for conscience. You scream "genocide" into a microphone the state itself protects, then sleep soundly in a democracy you spend your days trying to destroy, while millions across this region would trade everything they have for five minutes of the freedom you use to spit on your own country.

To you, Zohran Mamdani! You stayed quiet when we have faced massacre, when Islamic Republic assassins were sent here in New York to kill us, stay quiet now!

STOP lecturing us Iranians about peace.

I don’t feel safe in New York listening to someone like you, Mamdani, who sympathizes with the regime that killed more than 30,000 unarmed Iranians in less than 24 hours. You talk about “safety” of this beautiful city? Listen carefully; Safety without justice means nothing.
We Iranians do not allow you to lecture us about war while you had nothing to say when the Islamic Republic shot schoolgirls and blinded more than 10,000 innocent people in the streets. You were busy celebrating the hijab while women of my beloved country Iran were jailed and raped by Islamic Security forces for removing it. And NOW you find your voice to defend the regime? No. I will not let you claim the moral high ground.
The people of Iran want to be free. Where were you when they needed solidarity?

New York belongs to people who stand against terrorism not those who excuse it.

This city is stronger than fear.
Stronger than propaganda.
Stronger than you think.

Thousands take to the streets in Iran to celebrate the death of Supreme Leader Ali Khamenei https://t.co/upSXBuhjbe

[Ahmed Fouad Alkhatib @afalkhatib]

Mr. Mayor didn't want to speak to Iranian New Yorkers when the fascist regime slaughtered tens of thousands of their countrymen & women, but is only addressing the handful of Iranians in NY who may still be supporters of the Islamic Republic. Just like Palestinian lives seem to only matter to most when Israel is involved but not when Hamas is, the Mayor & hordes of politicians like him didn't care when masses of Iranians were butchered by the Islamist regime, but suddenly, Iranian lives matter when the US and Israel are involved. Comrade Mayor had nothing to say about 6 Arab Muslim countries being struck today by the Islamic Republic's missiles, during the month of Ramadan, nor is he addressing Arab New Yorkers about their nations being attacked by the Ayatollah's regime.

[The Wall Street Journal @WSJ]

Israel hacked a popular Iranian prayer app to send notifications to potentially millions of phones Saturday morning urging the country’s military personnel to defect from the regime and join a fight to liberate the country. https://t.co/osIRvGSmrz
