That is just political posturing from Russians to appear relevant in world politics.
Iran and Syria will NOT get any s-300. period.
Everybody can now see trough empty Russian talk.
This is just to get Iran to quit its lawsuit in international court.
Iran ,unless its completely stupid ,should not accept anything else but endure and finish the trial and buy something good for those billions in compensation.
If they accept s-300vm as replacement theyll wait many years for it ,then theyll have to sue them in court again because its a different system ,and the whole thing starts over. It will be the same story.
The Russians are just buying time because of $$$$ theyll have to pay,a very cunning plan.
Theyll lose in court soon and they know it.
Russian broke the contract and will have to pay billions.
Their loud-mouth and western apeasement has finally bite them in the ass.
Proof: both Venecuela and Belarus have got s-300vm and s-300pmu series pretty fast, without a problem.
So iran and syria (who ordered same systems before them) should have gotten them years ago if the Russians were honest in their sales.
I think Iran was very smart to sue them finally.... Nobody ,state or a private person ,want to get tricked, after signing a contract.
Im sure theyll be able to buy some good SAMs from other countries for that much money.
This is called realpolitik. You well know, that Venezuela and Belarus are not under UN sanctions, so they could easily got them as Cyprus, India, China, Vietnam and other clients. On the contrary, Syria and Iran are under UN sanctions, so there are limitations for armament deliveries. Intentions of West to make military intervention in Syria change the situation, that is why Russia slowly deliver bigger complexes as Bastion antiship complexes and used S-300 complexes. Russia know, Iran will be next and they give an offer first with additional Tors and now with S-300VM. To be honest, S-300VM is far more capable than original export S-300PMU1, which Iran order.
Iran and Russia are not allies and they don't have any pacts between them and they are also not enemies. They are neutral to each other and they are more on same side because of common enemy. Russia will defend their own interests and safety first even against UN sanctions if and when it is needed. Russia give Iran better help with helping them to develop and produce their own systems, because home made systems are immune on sanctions.
