pakistan: What is the problem with the region?

Why can't pakistan behave like on if it wishes to be called a 'responsible nation'?
Why is it so obessessed about its enemity with India? Why enemity?
Why does it have to counter India anytime/anywhere?
Why invest so heavily in terrorism?
I doubt if pakis support terrorism?
Why can't we work in synergy with each other?

PS: Couldn't call pakistan a nation. They probably need to prove it. Will someone vouch for pakistan?
