I know theres a lot of "it was the joos!" Out there but hear me out. This one lines up nicely.
Background - Russia has long propped up the Iranian regime as a counter to US/Israel in the region.
Premise - Israel had to neutralize Russias long range strike capabilities before risking a war on Iran.
Tactics - both attacks used infiltration and local drone assembly/attacks. Both totally novel and never seen before in close succession. Timng and tactics indicate the same origin.
Outcome - remaining capabilities moved to far east. Southbound ordinance would have to cross China, which is diplomatically touchy. Reduces but doesn't remove threat to Ukraine.
QED
Yes. Iran has been supplying them militarily and economically for decades.
They finalized a defensive pact just a few months ago: https://thegeopolitics.com/iran-russia-20-year-strategic-cooperation-agreement-key-takeaways/
I knew they were developing closer ties. I assume they might become even closer still thanks to being under fire from the same source. You could be right.
