It is not being ungrateful but disappointment. Your mentality of "terrorism will stay for decades to come" is not a good one. If people think this way they won't pay attention and act as terrorism happening is normal. We don't want that to be a norm in Pakistan. Just like we used to have mentality of "india can go ahead of us and be more developed because they are big country" made us go down the drain and look how we both compare today. Pakistan who was once way ahead of countries like South Korea, Taiwan, Malaysia, Indonesia is today way behind than even India, Bangladesh, Vietnam, etc.
