The Russian nuclear umbrella is a development John Kiriakou reported in a short broadcast recorded on 15 June 2025, two days after Israel began striking Iran.
The situation he was describing
Kiriakou opened with the state of play: Israel had attacked on Friday 13 June in what was presented as a pre-emptive strike against the Iranian nuclear weapons programme — a programme, he noted, that “the Iranians have said repeatedly over the course of decades” they do not have.[1]
He gave the casualty figures then available — “78 Iranians dead, more than 320 wounded uh versus three Israelis killed and and two dozen wounded” — and described a decapitation attempt that nearly succeeded, killing the military chief of staff, the head of the Revolutionary Guard Corps, the head of the nuclear programme and the country’s top scientist, carried out “primarily from inside Iran.”[2][3]
The umbrella
After reporting an IAEA finding of a nuclear leak at Natanz and noting that the site was not destroyed, Kiriakou turned to Moscow. “The Russians have said that Iran is under the protection of the Russian nuclear umbrella. The Israelis don’t dare use nuclear weapons against the Iranians because that risks the Russians using nuclear weapons against them.”[4]
The inference is stated as a foreclosure rather than a deterrent balance: the declaration takes an Israeli option off the table entirely.
The immediate aftermath
Kiriakou’s summary of the opening days was that the campaign had failed on its own terms. Iran had launched at least two waves of drones and ballistic missiles, hitting the Israel Defense Force and the Defence Ministry and destroying a surface-to-air missile battery in Tel Aviv; the Israeli government, he said, had reached out through third countries asking Iran to stop — “That’s rich. But that’s what they’re doing.” His verdict on the plan: “They thought they could take out the nuclear program in one strike. It didn’t work.”[5]
