I suspect that Osama had unlimited access to Pakistan and other countries like Iran. I heard murmers that he was in Iran. The compound was a central operations center fully coordinated with the Pakistan government.
I think we should not be distracted by all the other scenarios and look at this as a simple situation. OBL was furthering Pakistan's mission with the network he was able to provide.
You are correct about the OBL’s money that was being generated. Some of that money was probably coming out of the mosques from inside the western countries. This is money that went to the cause; using the Osama brand as a draw. I am sure it was a huge draw. I think Pakistan was aiding and abetting Osama for the “rent money.”
Probably so....Osama wasn't the brightest bulb of the lot. He may just have wanted and been satisfied to remain in their custody and have some resemblance of a family life...such as Muslims have. He'd been on the run for four years by then...especially if he did have serious health issues which many seemed to think. The one photo of the mansion showed a ledge with several medications on it. And there was hospital nearby for any treatments he may have needed.
But it would be interesting to see his face, even if bloody etc. Some might be able to determine if he was ill. Some of the last shots of him he looked pretty weak.
There was an interview with the Ambassador of Pakistan and the host asked him about the Billions sent in relation to the suspicion they were helping Osama. I was stunned he went into this rant about how it's the USA's fault the circumstances in Afghanistan, and with the Taliban, are such as they are..and war ensued. That this money is just the price of warfare to retain their help....which sounded like blackmail to me!
