Laugh all you want but in a real war missiles and nukes is what will matter, billions of dollars of matter can be turned to dust in a matter of seconds. Pakistan's strategy has always been defence (or enough offence to offset aggression - which in the threat of a nuclear strike, has been reached for a long time). What India has on paper is not what translates into the battlefield, never will India's full military might be subjected against Pakistan, whereas in any attack, the overwhelming might of the Pakistani Army will be thrown against the Indian forces; thus, India will need a much, much larger conventional advantage to maintain an invasion of Pakistan.
