Russia is not the unreliable partner, rather Russia only tried to be fair toward israel. However, as time progressed, israel showed it's nasty true self by actively supporting Georgia in the South Ossetian War. israel also showed it's nasty true self when it used clandestine means to transport weapons via Azerbaijan, through Bulgaria and into Syria, arming it's ISIS terrorists. One can liken the relationship of isis with israel, to what j@ckass evangelical-americans have with israel. And to top off its arrogance, israel used it's clandestine assets to start up a conflict between turkey and Russia, by assassinating Russia's Ambassador to turkey, in Ankara. Last but not the least, when israeli jets which conducted missile strikes in Syria, used for cover, a Russian Air Force reconnaissance aircraft when the Syrian Air Defenses engaged the pathetic israeli coward fighter-jets. As a consequence, the Russian reconnaissance aircraft was shot down killing 15 personnel onboard.@yavar
How confident are you Russian will not again screw this deal like they did with the S-300?
We have learnt in history, many times, that russia is a very unraliable partner, they cheated many times on Iran
Syria is still waiting for the YAK-130 they signed with russia ~ 10 years ago
+ lets not forget the joint Russia-Iran Fighter Jet Project which russia left because of the engines
+ the pressure from Israel/USA will be imense
Lets hope that Iran will be able to reverse engineer the engine, avionics, airframe... within 10 years after delivery of the first SU-35 and we may see an better, "iranian" SU-35 in the future..
A clear warning to Russia, israel is not your friend and they will backstab you the moment you let your guard down. As it has become abundantly evident. So continue to support that b@$tard-state of israel, will lead to your own detriment.
