Gadolhadorah:
Did Obama have a long term strategy of regime change in Pakistan (btw a US ally) when he sent his men to kill Bin Laden?
The reason it was done now is twofold.
One is in retaliation of the embassy attack (some US presidents, not all, dont allow the enemies to attack their embassies)
2, he showed up in Baghdad where the US has eyes on his whereabouts so they were able to easily find him and deal with him.
