You have summed up the situation completely but while putting many politicians behind the bar you have been soft on Nawaz Sharif's party.
Nope, use common sense. When I say Justice for ALL....how could there be an exception? ALL means everyone. Unlike IK and his corrupt buddies, I am not saying invest "HIM" and our corruption is a gift of God so don't even mention it. I didn't use NS's name in the list as he's been accused of every living breathing issue for a decade and a half. Every single military and non-military agency has been through their money trail, investments, homes, businesses, etc (Mushy and the time before, when he was forced out by the military). So during those times, Mushy and the previous COAS would've LOVED to hang him if real corruption was found.
In fact, when the Saudi's and the Americans called Mushy, that's what they asked. Mushy was adamant in saying " NS violated the law" and to that, both the messengers told him he should be well aware, that taking a life of a politician this time, extra judiciary without any real issues, will not sit well with the globe and just the sanctions alone would cripple Pakistan. It is then when Mushy gave up his ego and decided to do a contract with KSA and NS. Now you are seeing a repeat of that dramatic behavior, from IK's "Dog ate my votes" (AKA, rigging) to sit-ins on votes to now corruption. Its the same story different day.
But, if NS is proven guilty, hey, I want him to enjoy the SAME cheapest real estate IK and Tareen would, in the jail (its highlighly unlikely due to the past 20 years of constant investigation he went through). Same goes for anyone else in his party. In my books, the TRUTH matters and I will always defend the truth on forums. Corruption, doesn't exist in my books. Justice for all means put people to jail who've destroyed and stole Pakistani treasury's money.
Situation of India and Pakistan was pretty similar before the election of PM Modi ( While many Pakistani hate him for being a right wing Hindu, but no one has challenged his honesty or patriotism ). After Modi becoming PM, India gradually and slowly has started moving toward the desired path of good governance and economic development. Modi has been taking his time and slowly moulding the system by removing the corruption from Top. He is deliberately avoiding instant removal of top suspected corrupt bureaucrats and letting the investigative system and judiciary take its time. Since the whole system has been corrupted to the core including the judiciary, police and even media therefore any unexpectedly hard shockers ( of the kind that you have mentioned ) can literally rock the boat and may result in deviating from the desired course that the Nation has been set into.
That's the beauty of a democratic nation. India has made strives towards maintaining democracy. If Pakistan wasn't ruled by the military elite, it would have been turned into a little India. What I mean by that, is democratic, stable and economically prosper. But the past is the past. Its not too late. NS's policies and work is turning the tide. The new Pakistan others use as a "slogan" for their laziness.....is actually already been built by NS. One of other and most important reasons I support his government ONLY because the projects they have started, half of which, if completed by 2018, will form a backbone for a very fast growing economy. Remember, he is doing what others did not and could not do in the 70 years of previous rules of Pakistan. He's literally accomplishing all that in 5 years. So kudos should be given where they are due, no matter who does the work.
My goal on here is to write the truth and allow people to appreciate progress and understand growing countries resolve their internal issue within their Parliament, not outside on the streets like IK does. His behavior should NEVER become an acceptable behavior by a nation who wants to be modern, peaceful and stable!! Democratic people talk and negotiate all issues peacefully. Violence gives birth to extremism thoughts and later these can be channeled towards terrorism and that should NEVER be acceptable!!
If both, NS and the opposition truly work out this commissions scope and investigative powers and authority and make it independent, I think this would be a massive favor to Pakistan as people on the top would see examples and would start to end the corruption.
