What was the evidence that we gave Pakistan and Saudi Arabia that convinced them of Osama's quilt? They were the only two Governments that recognized the Taliban as the legitimate rulers of Afghanistan, but after seeing the evidence they decided to cut all ties to Afghanistan/Taliban even at the risk of having their people revolt against them. Why do you think that is? Must have been pretty solid/convincing evidence don't you think?
How would I know? Frankly I don't believe any was provided. Both have been told in no uncertain terms that we really don't respect their wishes either way and will attack them if they refuse to comply. Now you tell me: which do you think was more convincing? The "evidence" or the threats?
Since neither of us has seen the evidence, it's hard to say that Pakistan was convinced by the evidence. It would be easy for our government to claim they were convinced. They hold the two nations over a barrel.
