It WAS planned during Clinton's administration.
Bin Laden was angry with us because we had bases on holy ground, his homeland of Saudi Arabia. But you must ask why the oversight and cover up of Mohammed Atta by the FBI?

He had international pilot's licenses and was free to move in and out of this country as he pleased. He took many illegal flights out of Wally Hilliard's Huffman Aviation in Venice, Florida. The FAA and the FBI looked the other way, he had protection from on high. His deal was to ferry coke and heroin around. One of his flight buddies was Bin Laden's brother. Now don't go telling me, that someone didn't know what they were doing. They had PROTECTION.
