So in a way, what you are saying is that people who have been oppressed, have got 1000s of grievances, and are now extremely discontented with the authorities oppressing them - Should learn to fight their own way out of it all??? And so calling anyone in from the outside for support, now calls for a foul and red card in his game???
However India did this very thing in 1971, by “helping” (actually arming) the Mukti Bahini rebels in Bengal… So what’s wrong if Pakistan arms every Kashmiri?
Somehow, I feel that what you are saying, is a very naive way of thinking. Or, a childish ploy to turn off the support for the cause (which is making India blood)… Either way, is will never work. Just like the entire Muslim world felt about Palestine, Chechnya, and Bosnia, so too is the case with Kashmir…
