Your statement assumes that Pak became nuclear under Mush. The fact is the Pak has been nuclear for a while now... long before there was a Mush and it was NEVER ruled by fanatics. It has always been either the military or a civilian govt (ostensibly). The military ALWAYS controls everything and it consists of bureaucratic people like Mush who have vested interests.
That he has a pliant US administration who needs to show "victories" against terrorism helps him in his attempt to brainwash the world with his propoganda about how he is the only person who can save pakistan.
If he were to be assassintated another general will take over. I am sure the succession has been planned in exchange for loyalty.
US has no choice but to praise mush or else it will become obvious that US has too big a problem in Pak and no plan to tackle it. Much the way things are seen in India. But hey at least the Indians are not living in a dream world.
Excellent and comforting point. Thank you.
