Unfortunately Pakistan is a democratic country but do not have democratic leaders. The constitution of Pakistan is just a piece of paper for them. They come, govern, fill in pockets, believe them to be super power but nothing is in their concern for the growth and better of their so called nation.
What we need is to have fair people in this game of politics who are loyal and honest to country and want to serve whole heartily and fairly. That's why according to the polling results more than 80% Pakistani's are now more in favor of army rulers. Because their dictatorship is far better then these corrupt leaders.
But again, Martial law is never a favorable option for an underdeveloped nation like Pakistan.
