This acquisition must be seen in the light of recent news regarding chinese submarine actitivy. Pakistan’s buildup of Subs will also be countered effectively by this purchase. All in all a sign that Indian and US leadership see eye to eye on many of these issues.
I start to see India more and more like France just before WW-II. The Chinese are going more and more Fascist. The Japanese start to look more and more like the Brits at the time and Taiwan would be Sudetan Deutschland.
