Any politician worth his name is very careful with his words. So is NS. SS on the other hand is another story.
I am not against PA. I am against political role of PA and the mess that causes. Our history is a testament to that folly. One has to be blind to not see that. Only special interest groups peddle stories to confuse this fact. Sadly, many gullible / unwise / superficial people buy the flawed narrative and turn half-baked propagandists themselves.
Our constitution is great. It suits our environment and has been ratified by ALL the different parties / segments / schools of thought, ranging from socialists to ultra-conservatives. Casting doubts about our constitution is a pet project for special interest groups cited in the paragraph above. The people who framed our constitution in 1973 were not stupid. They had seen British India, struggle for independence, Pakistan movement, struggle to establish a new country, the vicissitudes of bureaucratic meddling and preponderance in politics, 1956 constitution and its violation by generals, Martial Law, rebellion in East Pakistan, break-up of our country, revolt against Yahya Khan, and then a provisional civilian martial law. They had a lot on their plate when they came up with 1973 constitution. Please have some respect for their experience, their intellect, and their effort. Any effort to frame another constitution would break Pakistan as it exists today.
Why is it that the calls for another constitution (and the problems this can of worms would entail) invariably come from people who are either related to PA, or have a soft corner for it? The problem is with their security-centered authoritarian world-view, and not constitution as such. Their efficiency & order related arguments are just gross smoke screens to hide elitism that can not flourish in democracy.
A little respect for constitution goes a long way in making a country system-oriented, civilized, & respectable.
