The question keeps coming up: Do you think this British thing is al Qaeda or Hezbollah? Answer: what difference does it make. They have their differences but when it comes to the West (and especially the U.S., the U.K. and Israel), THEY WORK TOGETHER.
Here is paragraph 4 from the June 1998 indictment of Osama bin Laden (italics mine):
Al Qaeda also forged alliances with the National Islamic Front in the Sudan and with the government of Iran and its associated terrorist group Hezballah for the purpose of working together against their perceived common enemies in the West, particularly the United States. In addition, al Qaeda reached an understanding with the government of Iraq that al Qaeda would not work against that government and that on particular projects, specifically including weapons development, al Qaeda would work cooperatively with the government of Iraq.
As the 9/11 Commission Report notes, moreover, it is now believed al Qaeda collaborated with Iran and Hezbollah on the Khobar Towers bombing in 1996.
