To believe there will never be another Kargil like event is to believe and have faith in the ego and greed of powerful men. For it is not the Pakistani people who have any interest in waging a war against India...a common man has far bigger problems, of mere survival, than the conquering of the world.
The misadventures that we seem to take every decade and a half has much more to do with the politicized nature of the Pakistani armed forces. Soon after the founding of the nation, the army took on a mythical status, not because of its exploits, but the first of the military dictators had staked his claim on the nation. Pakistanis saw the armed forces as the only defense against an aggressive and unpredictable India...in reality, that more accurately portrayed the Pakistani side. Military glory was the only way these generals could gain power and hold onto it...well if not really glory, then one feigned through propaganda. War became a crucial part of the "election campaign", for no man or woman would pick a general to fix fiscal policy and social issues...they were a necessity due to the constant threat of war. Were the threat to disappear, what reason would there be for an all powerful military?
As long as Pakistan functions under the rules set forth in the 1950s, aggressive military actions will always be a very real possibility...every ambitious new military leader will first look to carve his place in Pakistani lore, legitimizing his eventual reign. Thankfully for him, history has proven, only a war has to be undertaken (planning optional), the details of which can be manipulated to make the relevant leader seem like the second coming of Alexander the Great...a glory created from the blood of brave young men who would die defending, not Pakistan's honor, but the misguided ambition of their military leaders.
That is not to say all military leaders are of the same ilk. But unfortunately due to the formidable framework already set forth by the army and then cultivated over decades, it only takes one man every couple of decades; one man with ambition and greed...everything else easily falls into place.
