Bar Pakistan's role in America's war against terror, all other conflicts you mentioned were for a certain period. None of them have been eating away Pakistan from 1947 till now. Even Pakistan's role in America's war on terror started in 2003, not before that. If there has been one factor that has hurt Pakistan since 1947 till date, there is only one.
None of my business, just wanted to make my point.
Pakistan was never placed on sanction due to Kashmir conflict, not that I remember, correct me if I am wrong.
Pakistan fought two wars prior to Russian invasion of Afghanistan and Pakistan was doing way better than Indian during those time.
Pakistan's downfall began after Zia and excelled it during Afghan war, which was 10 years long.
Then came in sanctions.
Then in 96' came in supporting Taliban in Afghanistan.
Then came in Nuclear testing.
Then came in more sanctions.
Then 9/11.
Pakistan had supported insurgencies in Kashmir in 1989 for few years.
So supporting Kashmir struggle has never been a downfall of Pakistan, Sanctions have and mostly were due to in pursue of Nuclear weapons.
Now Pakistan have leadership, who genuinely wants to help Pakistan to become a stable economy of the world. Both establishment and elected government are on the same page, they both understand that Pakistan need to have security for the rest of the world to invest in Pakistan, Pakistan as a whole does not gain anything with supporting attacks on Indian army, particularly during the time when they need foreign investment. Pakistan gain absolutely nothing.
You are an Indian,whether like or not you are part of this conflict, and the only way to resolve this issue is by talk, so it is your business and if not then make it your business as both side need more loud voices who would rather promote dialogue than violence, because ultimately that will be the solution to it as soon as radicalized extremists government of Indian realized that this is the only option they have.
