The reality was the Russian Geran supply chain shared many, many, components with Iran's Shaheed supply chain.
And both were using the UAE to buy and smuggle Geran/Shaheed electronics from the West.
Iran has stopped the Geran/Shaheed supply chain by attacking the UAE.

Is this a coincidence that we in Ukraine are having a sharp decrease in the number of Russian Shahed attacks these days?
I mean, it’s very noticeable. Same goes about Russian massive missile attacks.
