You cannot compare Iron Dome which is for short range and indirect fire, and S-400 which is for (probably) medium - long range, and direct and indirect fire alike. compare it to arrow 3 maybe? david sling?..
It doesnt makes any sense... Bexause both're totally different Fighters... While JF-17's cheap Tejas's highly advanced & manueverabel with poweful missiles... While Tejas's mk1 variant is equal to jf-17's block 3 variant & tejas's the best aircraft of it's category (light weight) meanwhile JF-17's grounded for more than 13 month & has less combat range than of tejas & Jf-17's an medium weight fighter...(& Most advanced medium weight category fighter jet is Su-35,Rafale & eurofighter) So India's increasing the Indeginous components(even ejection seat, refuling probe & engine's would be chamged...nose cone's to be chamged & sensors-n-electronic warfare suite with jammers are already replaced with better Indeginous one)... Comparing both aircrafts is like comparing "nano with jaguar"!!
Haha thats so not true. The Russian Empire alone invaded the caucasus like 30 Times, they invaded Afganistan, Persia, the Ottomans.. The Soviets invaded Poland, Finnland, Afghanistan, Iran, they invaded Hungary, Romania and the czechs after they had anti communist revolutions. Modern russia invaded georgia, chechnya, ukraine and they also support shitty regimes (Syria,Libya) who wage war on others
