I am sure obviously you are joking, isn’t it? 
Kabhie tou apnay joke-mode say bahar nikal ayea karo bhai. I was putting facts in front of ehtasab so that he can think.
Anyhow, sometime I feel that when you put things you might believe on that too … so for your thoughts: You should know that Uncle Bush or America do not order but give incentives to people various group of people: One of their most popular and strongest incentive is to make the ruler stronger by keeping the military of the country out of their way. Corrupt politicians love this American incentive as they are always scared of the military of their own country acting against them and their corruption. It is just like having bigger gunda behind them to keep weaker patriotic armed forces within the country scared of them.
I could not see what incentive they can give to a man who was himself chief of the army staff. For him, only incentive could be stability and well being of the country as that man cannot worry about military takeover, being himself head of military.
Here are incentives that America gives or can give to various ruling class:
To corrupt politicians out of power, America gives incentive that USA would try to put them in power and money (USA gives that incentive to Nawaz Shareef and use to give that incentive to BB, all the time). These people go for American incentive as they want to do corruption but are worried about their own military throwing them out. They think that with USA behind them, military of their country would not act against them and their corruption.
To corrupt politicians in power, America give incentive that they would give them money and would make them stronger in power (it is incentive for corrupt politicians in power who are scared of army acting against their corrupt government). Again these politicians believe on USA because they think that with USA behind them, military of their country would not act against them and their corruption.
Give incentive to Kings ruling a country but are scared of their own military or do not have strong military loyal to them that could crush mass up-rise against them. They think that American military would save them if their own military or people rise against them.
Now, can you please tell me what incentive USA could have given Musharraf if military was under him? How could USA tell Musharraf that to leave hold of military and you will become stronger? Isn’t it ridiculous or does it takes lot of intelligence to understand that it is ridiculous belief.
