I disagree. you don't see this in the army. in the army, the soldiers seem to be more loyal to their chief than the constitution or the country. similarly, our political parties might have a million problems but there is little dispute over leadership. Zardari, NS, etc, enjoy strong support from their parties. so, obviously we can show discipline when needed.
Keep army out of it please and tell me single institution that has "loyals"? NS, Zardari etc they are dictators and this is not how the teams run. If their works were so loyes to heads how come we have unlimited Muslim leagues (from Junajo league gave birth to NS league and that gave birth to Q league and then it gave birth to Ham-khayal league and so on). Same is the case with PP and all other parties.
Its culture and its in blood..simple is that.
Unless you make any institution PROFESSIONAL, this will remain the same. You need to have a fit in or fk out attitude (thats what army has btw)
