Surprise Guest With Trump and Saudi Crown Prince: World Trade Center Developer Larry Silverstein

Fifteen of the 19 hijackers who committed the September 11, 2001, terrorist attack were from Saudi Arabia. That attack took down the twin towers in Manhattan that Larry Silverstein’s company, Silverstein Properties, had just taken control of with a 99-year lease. It took two decades to rebuild. It would be natural for Silverstein to hold a grudge.

But when Saudi Crown Prince Mohammed bin Salman shows up in Washington this week to meet President Trump, Silverstein, 94, will be there, said the developers’s son-in-law, Tal Kerret, the president of Silverstein Properties. Kerret, a former Israel Defense Forces officer, will be there too.

Kerret left unclear precisely what Wednesday’s announcement might involve. It could be a Silverstein Properties development in Saudi Arabia, which is undergoing a building boom. It could be a campus or health-care deal involving NYU, where the Silverstein family has long been active. NYU already has a campus in Abu Dhabi.

“My father-in-law always believed that the future has to do with connecting people,” said Keret.

Kerret made his comments Sunday November 16 on the stage at Klarman Hall of Harvard Business School, interviewed by Harvard Business School lecturer Jeffrey Bussgang during a daylong conference on “Jewish Resilience and Innovation” organized and hosted by the Jewish Student Association there.

Trump told reporters today that the U.S. will approve the sale of F-35 fighter jets to Saudi Arabia. That has raised some concerns that China could access the technology or that the sale would erode Israel’s military edge. Some have suggested making the sale conditional on Saudi Arabia joining the Abraham Accords. Trump’s May 2025 visit to Saudi Arabia, Qatar, and the United Arab Emirates was largely focused on getting those nations to pledge investments in the U.S. economy.

Another panel at Sunday’s conference was devoted to Israel’s startup sector. Yaron Samid, the founder and managing partner of TechAviv, said Israel has been “behind” on artificial intelligence. He said that gives investors an opportunity to get involved at valuations that are lower than if the companies were based in San Francisco. “We’re building foundation models in Israel quietly. We don’t have the hype,” he said. He said investors in the TechAviv network—including, he said, Michael Dell, Bill Ackman, Larry Ellison, Mark Cuban, and Reid Hoffman—want to invest in companies that will become Israel’s AI leaders.

“AI is just the wave of our lifetime,” said David Frankel, managing partner of Founder Collective. Frankel was introduced by his panel’s moderator, Harvard professor Paul Gompers, as the Tom Brady of venture capital. Gompers said he is writing a case on Decart, an Israeli AI company that Sequoia Ventures’ Sean Maguire and Dean Meyer liken to Google. (Okay, there’s some hype, just not as much as in California.)
