There's some truth in your comments. I'm not sure we owe each other anything. In reality, there are very, very few nations with whom America has had a long-term strategic relationship-Canada, Great Britain and Australia are foremost.
Probably Israel since the late 60s. Maybe Japan still. Perhaps S. Korea. Virtually nobody else in Europe. I doubt our relationship with India will ever truly be strategic or "all-weather".
Few other nations retain the same habitual allegiances to one another. China and Pakistan might come to mind but I really wonder if the firmness of that relationship has yet been tested.
All that said, America and Pakistan don't necessarily have to travel divergent trajectories either. I don't see straight though divergent lines. Instead, I see a common general pathway with moments in time where we close and then drift away as necessary by nat'l interests.
Only nations absolutely bent upon war with one another follow absolutely divergent paths and there isn't a single major state to which I'd ascribe that trajectory with certainty-not even India and Pakistan.
The real issue for America-and it exists for America's relationships with any evolving state, is with whom to have a relationship and when. You point out issues here-
"...Pakistan needs a fundamental change in the way it organizes itself and it's economy, in it's present form, it's a danger to it's own citizens and to 'others'".
Should we wait for Pakistan to discover its identity? Should we "help"? What's "help" anyway? Money spent hasn't proved the solution beyond temporal bandaids of dubious worth.
I'd submit that Pakistan must struggle with itself to survive or dissolve as a nation. It's not guaranteed. I don't believe America was "guaranteed" until the American civil war resolved forever otherwise irresolvable contradictions of purpose. I don't suggest that Pakistan must engage in a physical civil war but, minimally, a profound nat'l dialogue of absolute honesty is likely required.
Even finding those to lead that dialogue may prove a challenging task. That traces to leadership and is quite probably one of the issues faced by your nation-how to grow leaders that represent the divergent strands of all elements in society and providing them with an environment fostering meaningful exchange that benefits the entire polity.
Enough prattle but some really thought-provoking comments by you IMV.
