Pakistan is a dependent state since decades, majorly dependent on US (yeah whether one like it or not no matter who is ruling) and its affiliation or one should say subsidiaries, IMF and WB. US is the major contributor toward aid PK receive every year. In addition China's CPEC help with some breath from stressing economic pressures but that all loans...
Political stability in Pakistan means the govt. which is backed or endorsed by these two giants externally (mainly by US) and by military establishment internally. Unrest always starts internally, where establishment want full control and puppet try to resist... That's the naked truth rest all is just emotional slogans and political stunts...
