The issue is not about the "Modi government" or really any government, not primarily. It's about the Islamism and Islamist terror raging in the state, that makes it impossible for the Kashmiri Hindus to return.
The Modi regime had four years to do something about the Pandits. The Vajpayee regime had a big fat six years. Neither ever raised a single finger to take action (except for the Gujarati regime now in power paying online trolls to scream about the Pandits whenever anyone talks about Indian misrule in Kashmir and the plight of Kashmiris). The inference is clear: the Bhakt Jumla Party has no intention of doing anything about the Pandits. They are a convenient hammer with which to bludgeon dissent, no more.
