They have the capability to lead an offense but may not have the capacity to absorb the costs(military and economic) associated with it.I don't think any strategist will tell India to attack Pakistan. They lack capabilities to lead an offence.
Remember, they keep harping on the two fronts they created in their minds. They may win a conventional war against Pakistan but what will be left will not be sufficient to defend against China.
Although that is a fantasy scenario they created to justify their arms purchases.
