What level of action can India take to ensure Pakistan does not succeed with any riposte?
Outside of some Rambo shit, the only way out now is a tri-service level open-ended operation to degrade the entire fulcrum of Pakistani military activities aka war. Yes there will be casualties but there have been casualties even during the supposed peace time.
Every inaction strengthens Pakistani resolve to continue with its terror policy unabated. Until we can reasonably demonstrate the costs for pursuing 'bleed India by a thousand cuts' policy has unacceptable costs to the Paindu wardis, they have by default 'won'.
