... and there are plenty of them here who for some reason always think that Russia owes everything to everyone. Here is a confirmation of my long-standing thesis about Iran being a not easy partner. Obviously, Iran is an ancient culture and very proud people, but they are also extremely sensitive (understandably) about own sovereignty and entering any kind of alliances. Sometimes to own detriment.
Putin emphasized that Russia firmly opposes any further escalation between Iran and Israel. When asked what would Moscow do in the event of a targeted assassination of Supreme Leader Ayatollah Khamenei, Putin refused to even entertain the premise, calling it a “scenario I won’t even discuss.” Putin added that Moscow has not been asked to intervene militarily in the conflict and sees no reason to alter its current stance. While Russia has previously delivered air defense systems to Iran, Putin claimed Tehran showed “little interest” in broader cooperation. Instead, Putin advocated for mutual security guarantees that would protect both Iran’s right to peaceful nuclear technology and Israel’s right to security. He said Moscow has put forward several compromise frameworks to all stakeholders – including the US, Israel, and Iran – and held out hope that diplomacy could prevail.
I repeat again--you cannot impose yourself on people. If they decide that they can go it alone, it is their decision and it must be respected. Russia is ready to do her part if asked, she wasn't. That's your answer to why "Russia doesn't give S-400 to Iran". Because Iran doesn't need them, in their opinion. Stay tuned.
