Almost Complete

The UN nuclear watchdog has confirmed what everyone suspected but no one could prove for nearly two decades: Syria was building a nuclear reactor under Bashar al-Assad, and it was almost finished.

IAEA Director-General Rafael Grossi told reporters in Vienna on September 7, 2026, that inspectors who visited the site in August found a reactor in "a very advanced stage of construction." Not a blueprint. Not a plan. A reactor that was nearly done.

"Given the configuration, the technical features of that type of reactor," Grossi said, "this is a reactor that is very efficient in the production of fissile material that could be used directly for the fabrication of nuclear weapons." Building it, he added, was "a very important step."[1]

The reactor was in Deir el-Zour, the same site Israel bombed in 2007. Syria leveled what remained and spent years stonewalling the IAEA. The agency declared in 2011 that the location was "very likely" a nuclear reactor built with North Korean assistance. But without access, it could never confirm.

Then Assad fell in December 2024. The new government in Damascus made what Grossi called a "courageous decision" to let inspectors in.

What they found went beyond the reactor. The IAEA discovered a fuel fabrication plant, where nuclear fuel for the reactor was being manufactured. A separate location held nuclear fuel, uranium scrap, and waste. And somewhere in all of it: about 73 tonnes of natural uranium metal.[2]

Grossi also suggested the Assad regime may have carried out explosions at the site to destroy evidence before inspectors could arrive. "It is very possible and cannot be excluded," he said.

The IAEA board is expected to vote this week on a draft resolution to close the Syria nuclear file. Grossi praised Damascus for cooperating and said the agency would continue working with Syria to keep the material safe.

So: a secret nuclear reactor, built with North Korean help, hidden for almost 20 years, almost operational. The only reason it never went live is because Israel blew it up in 2007. And the only reason we now have confirmation is because the regime that built it collapsed.

How many other sites like this exist, in countries where the regime has not yet fallen?
