Since the Bin Laden planned attack happened on 9/11/2001, why would a daily briefing in April 2004 have anything to do with Bin Laden attacking again? You probably just had a typo and the brief was 4/10/2001, right? That was the same kind of warning that had been made many times before, some to Bill Clinton. What would you suggest that Bush and Bill Clinton have done? As you point out, the briefing warned that "Bin Laden determined to strike in US". Strike what? Strike where? Strike when? Strike how? So if he strip searched all plane, train and bus passengers, that would have been alright with you? If he had ordered every piece of luggage or bag be dumped out and searched thoroughly, that also would have been ok with you? If he had acted on such vague information, you and almost every person in the country would have been very upset with him and he definitely would have been a one term president.
