The encirclement of Pakistan is now complete. India now has to spend a fraction of its military budget building up and training the Taliban and it will split Pakistan's forces on two opposite wings.
This gives a launchpad for them to do in KP/Balochistan what we were doing to Indian Punjab and Kashmir in the 90s and early 00s.
At the same time, because its not going to be Indian nationals themselves crossing over to fight Pakistan, they will maintain deniability in the world whenever Pakistan cries about Raw/India doing terrorism in Pak. Unlike in our case where we trained our own countrymen in madrassas to go do 'jihad' in Kashmir.
Normally as a defence fanboy/armchair general this is the part where I give my 2 cents on what Pakistan could do to counter all this but right now we have more important things to do. Big boss is doing population control now since hes tired of being a diplomat.
But lets see anyways. We could counter all this by doing our own version of Op Bandar and Sindoor on India everytime we face significant casualties from the random blast/attack but then what is the gurantee Pakistan comes out on top against a country 7x its size?
Countering via development of Tribal KP areas and Balochistan is also impossible now. That will not instill patriotism in them in what they will view as a Punjab dominated country. Just look at the 'Us vs Them' mindset of some posters here when they talk about baloch/pashtun.
