It is not hard to defang Pakistan off it's nuclear weapons. Look hard enough, track and list scientists, workers and understand their chain of command. What visible may not be the actual and every layer must be exfoliated.
Dedicated precision delivery package to hit facilities, launchers and launch sites. Over pack anti-ballistic missile defence grids for the areas which can not be covered.
Know their contingency plans, follow what they will do in case they see it losing because most of the windows to attack us will be gained during or after the chaos. Check their allies, predict global reaction and place plugs on them.
Create multi-level deceptions, script internal strives, geo-politocal events, social media storms and other distractions.
Be ready for collateral damages, spare money to compensate them. Plan during water adequate seasons. Compromise their leaders and plant them when they fall. Invade, contain and have exit plan.
Improve internal security for sleeper cells and lone wolf attacks. Have leadership benches ready if main leader is taken down. Inform and ready population for long and limited insurgency in different parts of the country.
