Modi has weaponised the killing of Muslims for his own personal political calculus for decades now, what has changed is simply the scale of that calculus now. Starting from Gujrat, to now Pakistan, his political needs and appetite has only gotten bigger.
This has been at low cost to him personally and his supporters to date, an entire political empire in India has been built on the complete disregard of Muslims and our values, and the use of their lives and well being for their political enhancements of groups like RSS in India. Modi feels emboldened by what he has seen Netanyahu do and get away with.
We are at a difficult juncture right now, this is not what Pakistan needs now, that ideology is now crossing borders and now is starting to affect Pakistan. That is the sad reality of where we are.
What has to change, is the political calculus of the RSS and Modi, once that forces a rethink and a world view change that there are limits to how much they can weaponize the targeting Muslims of political goals.
Pakistan has to push this calculus back into India to make sure it does not affect Pakistani's and for that, there will be a price to pay unfortunately both for Pakistan and India. That has to be a heavy price so that they don't think of doing this again.. While the first round has not gone well for India, they may have some successes in latter rounds. There will be multiple rounds before this stops, lets not kid ourselves. We just have to accept there will be loses to protect Pakistan and its people but accept that this needs to be done to protect Pakistan.
What is required now, is to increase the costs of this action such that Modi never looks Pakistan's way again. Unfortunately, 'restraint' has emboldened Modi, not tempered him.
Pakistan does not just need to prepare for the retaliation and to make sure it exacts a very heavy cost, but have active plans for the next 3-4 rounds of escalation and retaliation. India has had first mover advantage for sure, and they may have prepared multiple rounds of escalation as shown by the drone attacks, and Pakistan now needs to do the same.
Gujrat, the home of Modi needs to pay a price. There will be military targets there.
India as gotten as far as Rawalpindi, that wont be lost on anyone either.
Pakistan needs to formally declare RSS a terrorist organisation now and make clear to the world it views RSS as a terrorist organisation that it will take military action against at its discretion at any time.
We can question why these target plans and actions are already not in place later, but right now, the focus is on preparation.
