Pakistan has to declare its nuclear doctrine, makes it a lot clearer for everyone, no point in everyone second guessing it, the second guess will always be threatening to the whole world which again could be counter productive. If its arsenal is for India then say so, Otherwise everybody would want to believe that its a rogue state with a big nuke pile with no clear cut strategy.
Is it when India would attack PK conventionally than PK would use its nukes? or will it use it without any provocation, just to start a war at the behest of its ally?
Will it use its nukes when there is a war between India and china? will it use it against India if it is attacked by the US?
Or will it do it if its threatened in any way, a open doctrine will help in engaging with PK more responsibly, we will know our limits and will strive to not cross the limits, but PK has to tell us that these are our limits and u will face nukes from PK if you cross them. A blind game can go only so far. India has to know its threshold vis a vis PK so as to be alert to not cross it. India has stated that it has a defensive posture with its no first use policy. Everybody has to know PK's doctrine which will help in projecting yourself as a responsible state. The current image carried by the world wrt PK could be wrong, but u r the one to tell us that.
