Now that Bin Laden is dead, many major questions remain unanswered. The biggest one is what is Pakistan's role in all of this?

To me it looks like Pakistan first harboured Bin Laden and later on (perhaps upon American pressure) sold him out. Does anyone come to the same conclusion? Here is my reasoning:

1. He lived in a fortified mansion outside of the Pakistani capital, surely someone knows that's his castle.

2. To build such a castle there, someone in the Pakistani government would have sanctioned that Bin Laden can stay there.

3. U.S forces can enter Pakistan unopposed means that country allowed them to do so.

4. Pakistani forces allowed a foreign military force to operate in their own soil is a disgrace to its own sovereignty (do we allow Amercian cops to make arrests in Canada?)

5. This means Pakistan kind of grudgingly allowed that to happen (i.e., do what you must do and get it over and done with kind of attitude).

6. Conclusion: That all pointed to a Pakistani sell out somewhere.
