Musharraf is a sensible dictator, he has withstood challanges so long and tactically, he supported USA and rest of the world when the warn in Afghanisthan started. This has earned him a possible safe haven in USA. With the way things are going on in Pakistan, Musharraf will try to hold on till his Army can sustain the pressure. When the Army begins to loose hold, Mush.. will have to go somewhere. Saudi Arabia is a not an option, India will never harbour him, China do not want to do anything with him and for Afghanisthan,,,,, if he went there, it will be his end....... the only other country that can and will bail him, will be USA. Musharraf will encash the cheque of gratitude that Bush/ American government owes him. So this is a make or break game for Mush.... If he wins this round, he will hang on in Pakistan, if not, he will leave Pakistan. You might wonder, why not UK. UK has a large Pakistani population where he has equal chance of trouble as much as support. USA is a large country and he can easily melt away in the countryside.
Mush has already invested heavily in USA, if we have to believe newpaper reports. Lets keep fingers crossed and see.......
