Why the US does not want India to buy Russian S-400 Triumf missiles

While India is all set to finalise and sign the deal with Russia for buying the lethal S-400 Triumf air defence missiles (NATO code: SA-21 Growler), the United States can use the Countering America’s Adversaries Through Sanctions Act (CAATSA) to stop the defence agreement.

However, Defence Minister Nirmala Sitharaman has made it clear that the US cannot stop the deal as CAATSA cannot be imposed by the United Nations and so India is insulated from it.

But international defence experts have told Russian news website Sputnik that the US has several reasons to stop India from acquiring the Russia air defence missiles which are way ahead of similar western systems and can prove to be a game changer in the event of a war in the subcontinent.
