INDIA buying S-400 Defense system

 

lets start i thought first to make a blog on S-300,S-400 and S-500 then i thought nay they are all the same but more improvements and advancement and made to improve their capability and power so they are technically all the same but like other weapons improvement are made over time so lets start talking about the topic India has bought S-400 defense system you think this will make Pakistan worry but it wont i will tell you 3 reason why

1)Pakistan has mirv technology and i dont think S-400 could work against mirv     
2) Pakistan has also gotten some technology from US which can fool defense system and the S-400 missile will nearly miss that missile i am not positively sure its true but the third one is for sertain
3)china air craft carrier destroying missile which are made certainly to attack against these kind of defense system
