How Trump Took the U.S. to War With Iran

“Mossad’s intel indicated that […] with the impetus of the spy agency helping to foment riots and rebellion an intense bombing campaign could foster the conditions for the IR opposition to overthrow the regime.”

Who was the intended audience of PRISONBREAK and other ops? Iranians, or Americans?

Iran is the worst-case scenario for everything we’ve warned about: AI fakes, real footage dismissed as fabricated, and a regime that engineered the doubt itself.

“The regime controls who gets to document and what gets documented.”

1/ NEW: There’s currently a heavy push over X in support of (1) the ongoing attacks on Iran (2) Reza Pahlavi. It’s hard to quickly quantify this wave, but anecdotal evidence shows that the main support hashtags - as well as by the *real* people promoting them - are also pushed inorganically.

‘After the blackout, they really started killing’: horror... Human rights groups and Iranians with satellite links have detailed the regime’s bloody response to protesters after its internet shutdown cut off access to the outside world

"Five days later, the same doctor came back online long enough to describe a nightmare scenario: the first thing he told Qorashi was he could still see “blood in the streets”, during his journey to work at the hospital."

Starlink terminals rely on GPS signals to locate themselves and connect to satellites. By disrupting these signals, Iranian authorities can render the devices unreliable without touching the satellites themselves.

When Russia tried similar jamming in Ukraine, SpaceX responded within hours with software updates that restored service. So far, no such fix has arrived for Iran. SpaceX has not commented on the disruption.

Amidst mass killings and internet shutdowns the Iranian regime has also found a way to jam access to Starlink:

1/ Russian disinfo sponsors can’t believe their luck at the chaos spurred by their American counterparts. Not only politicians, but their tech enablers too, of course.

Meet “Budjetti”. “She” is on X, of course. Openly antisemitic, racist, anti-Ukraine. And completely unchallenged.
