We should all think even if india manages to nuke pakistan & effectively stops it's missile entering india through anti missile shield,but india cannot stop the nuclear fall out from pakistan,as it is our neighbour .There can be a shield against missiles but there cannot be a shield for nuclear fall out & radiation.So there can be a winner in case of a conventional war ,but in case of nuclear war there is no winner ,both sides are loser either directly or indirectly.So i personnaly believe india should n't do any miltary attack in case of future pakistan terrorist attack,but instead make pakistan collapse as a failed state by fair or unfair means .
1.India can collapse pakistan by promoting instabilty in pakistan by supporting baluchistan & it's people's freedom struggle
2.India should create a propaganda that pakistan is a terrorist state & it's nuclear weapons are a threat to entire world.India should convince america to take control of pakistani nuclear weapons
3.We can turn the pakistan people against their own army ,as after Osama death by USA & raid of terrorist in pak naval base pakistani people have lost confidence in their own army.Indian Army chief was quick to capitalize this situation ,he deliberately said that indian army is also capable of carrying out usa style operation in pakistan,the purpose was to humiltiate pakistan army & to add salt to their wound & make pakistani people lose their confidence in their army.
4.India know pakistan's economy depends upon foreign aid for their survival,india is currently the world's biggest buyer of weapons as it has a strong economy to sustain it ,but pakistan in order to attain parity with india is alloting the aid which is given by international community for the welfare of pakistani people for buying of weapons.This is creating anger & frustation in the minds of people.Pakistan is already reeling under high inflation ,severe poverty & is economy is already under debt.so if pakistan wants to do any kind of arms race with india it would be suicidal for it's economy .
5. Another important weapon is water ,india can easily divert pakistan's water by building dams & reservoir,but i personnaly believe india shouldn't use water as a weapon ,as other neighbours like Bangladesh would lose faith in india
So the best policy for india against pakistan would be Wait, watch & Make pakistan collapse policy,not cold start doctrine or surgical air strikes in pakistan.
