U.S. had had some prior warnings about bombings. USS Cole and in 1993, the bombing at Trade Center
And they were given to the GWB administration upon the transition period, it was the responsibility of GWB after 1/20/01. He decided to do nothing about it and manypeople died. OBL was not Id'd as the Cole attacker until GWB became president. OBL was a CIA asset in the GHWB days, whatever happened there I dunno...
