Engaging with Taliban means engaging with ISI.
With the fall of Kabul, there is complete control of ISI over Afghanistan just like it was from 96-01. We do not need to engage with scums at all, we didn't engage with the 96-01, and still did fine. The source of power of these ragtag scum is in Pakistan, strike at the source.
And it seems quite ridiculous to me when we talk of interest. Indians common folk, NRI's, Government, Judiciary, NGO's, Public Institutions, Private institutions do not even work at 10% of their capability towards securing India's interest; so this interest business is a very intelligent-sounding talking point, but when pragmatism set in, the state is just hopeless.
