And this is exactly what the system needs, a shake up from a political party rather than Army or ISI. You can raise your voice in the parliament for sure, there have been several genuine and honest people who tried to raise the voice in parliament and where are they all today?? Theoretically you are absolutely right, change must come from within the system but practically you have to enforce some of the changes. Power is something people do not give up voluntarily especially if it’s used/abused for personal benefits. Why would Nawaz & co care about electoral reforms or independent NAB/Police/NADRA etc? You can cry your heart out in parliament but it would NEVER happen as it goes against their interests, some of these things have to be enforced (With the hope that Army does not interfere).
