Just for the argument sake...On the contrary imagine if United Hindus had confronted Mughals. These riots would never have happened and Bharat's western border might be stretched till within A'tan.
It's better to talk about practical solutions. In my opinion following changes could lead to lasting peace: 1. Declare India a Hindu state. This, initially could lead to minor hick-up, but 'll eventually pave the way for lasting peace. Because Hindus 'll feel secure in their only motherland, people 'll have ALL around devt., and there won't be any need for riots. 2. Break J&K into 3 parts. Let article 370 (temporarily) applicable to Kashmir only. Take out military of Kashmir and put it on it's border to ensure that trouble does not spill out of Kashmir. 3. Educate Kashmiris that if they become part of Pak, they would face discrimination. Because for Pak Govt, only Punjab is Pak and rest of the area does not count. Hope better sense prevail and gradually remove article 370. 3. Check inflitration on B'desh border, issue shoot-at-site order, remove all illegal people (use chinese methods). 4. Listen to NE's local people concern, provide them all round devt. Hopefully this will reduce terrrorism in NE.
Critical point is doe some analysis, develop a plan and start implementing in small phases.
