Actually India can crush Pakistan within one week. Not vice versa but they can do that definitely today.
"Despite the seemingly dramatic increases in its defense spending, the Indian military—in particular the Army—faces
numerous capability shortfalls that would
hinder military operations against Pakistan.
The large number of obsolete tanks, armored vehicles, and artillery pieces, not to mention critical shortages of ammunition and air-defense assets, raise serious questions whether India can undertake large-scale military operations at all, let alone whether ongoing defense modernization really is sharply shifting the conventional balance in its favor. Although Indian defense spending has gained attention worldwide, much of that money has been spent merely replacing obsolete weapons and equipment.
The most visible manifestation of the “hollowing out” of the Indian Army occurred in the aftermath of the 2008 Mumbai attacks, when then Army chief General Deepak Kapoor reportedly was forced to admit to the country’s political leadership that the Army “was not ready for war” with Pakistan in retaliation for the terrorist attacks.
Indian response time will also provide a buffer for Pakistan to respond.
Based on the aftermath of the 2001 and 2008 terrorist attacks, the Indian army would require several weeks before it could hope to initiate military operations. Although reducing mobilization time is a key aspect of the “pro-active” strategies, offensive forces have not been pre-deployed in the border region, nor will the army’s efforts reduce the amount of time the country’s political leadership requires to deliberate before choosing to employ military force."
