But the question is when will this happen infact separatist movement in india is at a decline it was at its peak in 70's 80's ....so i guess it will not happen anytime soon.....this is what wikipedia says

Many separatist movements exist with thousands of members, however, some have low local support and high voter participation in democratic elections.The Khalistani Insurgency in Punjab was active in the 1980s and early 1990s, but is now largely subdued within India. Insurgency in Northeast India involves multiple armed separatist factions operating in India's northeastern states, which are connected to the rest of India by the Siliguri Corridor, a strip of land as narrow as 14.29 miles (23.00 km) wide. Northeastern India consists of seven states Assam, Meghalaya, Tripura, Arunachal Pradesh, Mizoram, Manipur, and Nagaland. Tensions existed between insurgents in these states and the central government as well as amongst their native indigenous people and migrants from other parts of India. Insurgency has seen rapid decline in recent years, with a 70% reduction in insurgency incidents and an 80% drop in civilian deaths in the Northeast in 2019 compared to 2013.[1] The 2014 Indian general election the Indian government claimed it had an 80% voter turnout in all northeastern states, the highest among all states of India. Indian authorities claim that this shows the faith of the northeastern people in Indian democracy.[2] Insurgency has largely become insignificant due to lack of local public support and the area of violence in the entire North East has shrunk primarily to an area which is the tri-junction between Assam, Arunachal Pradesh and north Nagaland.[3] Jammu and Kashmir has long been wracked by the insurgency since 1989.[4][5] Although the failure of Indian governance and democracy lay at the root of the initial disaffection, Pakistan played an important role in converting the latter into a fully developed insurgency.[6][7] Some insurgent groups in Kashmir support complete independence, whereas others seek accession to Pakistan.[8][7] More explicitly, the roots of the insurgency are tied to a dispute over local autonomy.[9] Democratic development was limited in Kashmir until the late 1970s and by 1988 many of the democratic reforms provided by the Indian government had been reversed and non-violent channels for expressing discontent were limited and caused a dramatic increase in support for insurgents advocating violent secession from India.[9] In 1987, a disputed State election [10] which is widely perceived to have been rigged,[11][12][13] created a catalyst for the insurgency.[14] In 2019, the special status of Jammu and Kashmir was revoked. Since then, the Indian military has intensified its counter-insurgency operations. Clashes in the first half of 2020 left 283 dead.[15] The 2019–2021 Jammu and Kashmir lockdown was a security lockdown and communications blackout that had been imposed throughout Jammu and Kashmir which lasted until February 2021,[16] with the goal of preemptively curbing unrest, violence and protests. Thousands of civilians, mostly young men, had and have been detained in the crackdown.[17][18][19] The Indian government had stated that the tough lockdown measures and substantially increased deployment of security forces had been aimed at curbing terrorism.[20] The revocation and subsequent lockdown drew condemnation from several countries, especially Pakistan.
