No Wrong Again -
India not only buys Russian, also French, Israeli, Italian, German, Swiss, USA, British & the list continues forever. And also develops its products a bit above the best in market. If Indian developed product is not the best in world, we buy the best product - whoever makes them, like we choose Rafale, S400+, Apache etc thx for your fake worries.
Unless you are worried china got a counter to every best tech developed across globe.
Atleast India has the option for all the best tech (minus china), but poor you only limited to one set.
