You've gone out on the occasional limb before now, Tom, but isn't there just a single, niggling neuron in your head at the moment which is saying "This is a really dumb thing to double-down on"?
Everyone knows that USA is the single most powerful ..... (yadah, yadah yadah)... and so forth, but Iran is no slouch. Despite blockades they continue to supply the Houthis with cruise missiles, ballistic missiles, drones, comms, intelligence and cash. You seem to be suggesting that because Yemen doesn't make cell-phones that they are incapable of being provide intel by a third party. How about they get phones from Russia, or China. Or Iran. Just a second, email coming in from Kim Jong Un.
Neither Russia, China, or Iran invented the internet or the cell phone, or low level chip design. That was done by the US Government, who purposely pushed its development and and design at the direction of think tanks and visionaries, under consistent government funding and guidance. For decades the US Government funded Bell Labs, Arpanet, IBM, Intel, Apple, and many other tech progeny. If you think that they didn't think to put in exploitable back doors at every corner with plausible deniability, designed to propagate down to manufacturers, you would be wrong. Deceitful tacticians and spies is simply who they are.
From purposefully imperfect random number generators for encryption, to special hardware, special software routines, to compromised telecommunications hubs, the countries of the world have paid the US Government through its companies and foreign subsidiaries to integrate and maintain back doors into the world. Snowden says that the US Government has access to vast foreign and domestic data that is supposed to be private and encrypted, and that people are often fooled into a false sense of security.
I cannot readily proclaim what technologies Iran has contributed to the world, so I wouldn't expect them to have a similar exploitation of technology. The letters NSA and CIA are universally feared and respected. The intelligence capability of the USA is the goat beyond goats. All other countries fall in line and cower before its greatness.
