Well, sir, I'm not questioning your resolve and your motives. You want to accomplish something good by any means no matter how extreme. Perhaps it is the way to go but perhaps it's not.
But your entire plan sits on an assumption that no one will come to their rescue. Maybe you are right, since you are willing to bet your life on it. After all, Musharraf did remove Nawaz successfully without facing any problems. But you can't argue that times have changed since then.
Sure people hate the politicians in principle. But that's why they have their paid goons and the jiyalas that can take to the streets for them. Removing so many people simultaneously would also leave a huge bureaucracatic void that if not filled would effect the normal people and their lives. Which by your plan you don't want to do. So you must have some amount of compitant folk on your team to fill in at least the important slots.
The response of the international community can be argued. You might be able to convince the West of the urgency in tackling corruption and thus terrorism. But at the end of the day, private investors wanna know what will happen to their investment and business. China must be ensured their 50 billion dollar investment won't go sideways in your revolutionary aspirations.
To close it off, it's one hell of a leap of faith you'd be taking. And it won't be your life you'd be putting on the line, but hundreds of millions of Pakistanis', if even one thing were to go wrong with your plan. Perhaps that is the reason why Mushy couldn't go the distance.
And my apologies for adding ten whole years onto your age. Also, hope you consider staying on this forum a little longer. Your posts are always a great insight pleasure to reading.
