India crossed INTERNATIONAL BORDERS and invaded Pakistan twice.
Once in 1965, when it crossed INTERNATIONAL BORDERS and invaded Lahore, Pakistan.
The second time was in 1971, when it crossed INTERNATIONAL BORDERS and invaded East Pakistan and broke Pakistan and made Bangladesh. The same India is dreaming for Balochistan province of Pakistan.
SO yes, India is the biggest threat to Pakistan.
No other country has done to its neighbour what India had done to Pakistan.
We Pakistanis will never forget. We will even teach our children and grandchildren not to trust india/indians.
Not to mention the hatred Indians have for Pakistanis and Muslims in general as evident from indian senior member kinetic trolling account and his posts.
By the way, we have only internationally recognized disputes with India and no other country. We wish all our other neighbours the best. We Pakistani Muslims will not fight our own people for some one else's war. This is what our enemy, India, wants Pakistan to do. Having a neighbour like India on our eastern and western borders is the worst imaginable thing for Pakistan. Thats why fighting the Afghan Taliban is not in Pakistan's interests. Afghan Taliban are the only people who will not allow any indian presence in Afghanistan.
