What happened to Imran Khan is similar to what happened to and continues to happen to world leaders in unstable countries where the west financial and/or national security interests - sloppy regime changes.
As far as whether or not this turns out for the people of PK, we will never know bc he was nto in office long enough to do anything meaningful. PK needs like 20 yrs of stability to see any real progress.
I will say this - Imran Khan was very popular among the young, middle class types I know in PK (bc he is a populist), but not liked by western establishment governments. Take that for what it is worth.
