I asked for proof that a senior Pakistani politician has threatened to nuke India, I have no interest in the ramblings of some delusional moronLOL....This week itself a Pakistani politician talked about hoisting Pakistani flag at red fort. Former Pakistani defence minister Khwaja Asif talked about using nukes on India on a live TV conversation. As far as insurgency in India is concerned. It is well known fact that Pakistan provids men and material to keep Kashmir insurgency alive. Pakistan also supported Khalistan insurgency in 80's Also Pakistan is running Referendum 2020 program which was first announced by Pakistani Sikhs at Kartarpur sahib in Pakistan. Also you guys supported insurgency in North East starting from 1960's. As far as retaliation is concerned, those who know about Khalistan insurgency will know that the insurgency ended in 90's after a meeting between RAW and ISI chief. ISI withdrew it's support for Khalistan movement and in return Indian CIT-J team agreed to halt it's operations in Pakistan.
Except Kashmir and Naxalite-Maoist insurgency all other movements are breathing their last and have lost their relevance. After elimination of Garo militants last year NSCN(K) is the only capable group left in North East that too has been divided into Indian and Myanmar faction all thanks to engineering by Indian intel agencies.
