Problem with bloody revolutions is that you need another bloody revolution to remove the previous revolutionary leadership from power if they go off the track.
For example,Iran will need another bloody revolution to remove Mullah's regime, if they go off the track
China will need even more bigger bloody revolution to remove Communist if they go off the track.
But in democracy,power keeps on circulating thus any change can be brought with rather Peaceful methods.
How much IK has spent on Research projects in KPK?
How many people he has brought out of poverty?
How much he has reformed KPK police to make Justice affordable to every one?
Fact is that we need someone even better than IK to bring an actual change in the country.
