From what I am reading, Russia is no longer reliant on Iranian Drones. I guess Russia can take a page out of the playbook and start selling Drones and what not to Iran now.
Those drones are not overly complex to make, they can just as easily produce them in Russia vs Iran. 3 years into this conflict, Russia obviously is producing probably a large quantity of such drones and then supplementing that with imports from Iran/China.
