No you are wrong. Patriots and THAAD performed way better then Iron Dome and there is not even comparison. The Houthis never succeed except in very few instances and life is normal in KSA perhaps due to being a larger country but Israeli cities got more or less savaged all cities including the far way Haifa saw impacts and people were in bomb shelters literally. There is no compariosn.
S-400 is unproven and I can already tell you it is a fraud system like all Russian systems. I have no idea how the S-400 got overrated this much and I think it has something to do with it getting alot of media coverage due to the Turkey-US-Russia-NATO dispute over ''Oh don't buy it and Oh I am gonna buy it thing'' got to much unnecessary media coverage but Turkey didn't buy it either for it's capabilities but it wanted to copy aspects of it in order to finish developing it's own Air defensive systems it wanted some secrets from it.
Not because I am American and biased but the US still has the best defensive systems
Thaad is specifically for bmd type roles , so claiming it superior to iron dome is not correct imo , both are for different role and different categories .
Patriot is a prove system but airspace denial ranges are limited and it's bmd capabilities are much better than normal air defence .
Unlike s 400 , which might be unproven but a inclusive multi layer system which will give us some insight in deveolpment of our indigenous layered air defence for integration and operation , also it will help in pointing out shortcomings faced and we can work on that in indigenous system .
Also it will take time for indian system to be inducted and online ,till then it can serve purpose .
Thaad in comparison is a particular system , good yet standalone if inducted in indian ad role .
We are not traditional operator of US tech , which is expensive too , so integration of thaad would haven't bore any fruit , we won't be importing any long range ad afterwards ,so it makes sense to integrate with existing system .
Turkey wanted something russian as fear of another coup and to shoot down own AF in case of coup like he did last time
