This is called hands me down technology . A Jewish President is running around the world asking for weopons and money but Netanyahu does not give him time since it is beneath his stature so he has to delegate often but still he has to keep Zelensky afloat. in return Putin is doing everything to push these muslim countries towards Israel. This is called exchanging Science with Soft Power.

Putin derives his legitimacy from this combination and there many tweets like where Tesla Cyber Truck were parked when Putin was in Astana. or these fighter jets were flying until touch down.
