Yeah - I don't know. I think there's a combination of a lot of things but putting it down to Trump seems a little far fetched. I would put Trump's effect fairly down the list of reasons as to why this has occurred, sure it *may* have had some effect, but it's like the 5-6th thing on the list, imo.
Firstly, Modi's hard line approach during the first term hasn't helped and has slowly turned the heat up since he was first elected, in addition the BJP ( Modi's party) has always had this in it's manifesto ( and has been for years) and the resounding victory that the BJP had in the recent election with *terrible* results for the opposition has allowed Modi to do this without any fear of a proper push back, Congress barely has a functioning head of the party at the moment.
I'd also read Arundhati Roy's piece for the Times on this ( Imo, a lot of regional conflicts are looked through the lens of outsiders i.e. people not familiar with the history of south asia ( more bluntly by reports/ historians that are on the other side of the world), but I think Roy does a really good job of giving the required context from the ground so to speak)
It's pretty grim at the moment. I don't know how this gets better for the people of Kashmir. The election and my vote a couple of months ago felt so useless given that the state I vote is pretty much the BJP heartland. Sigh.
