Remember when nineteen Islamic fundamentalists hijacked four airliners and took out the two towers of the World Trade Center and part of the Pentagon? Remember when it was only through the bravery of passengers on United flight 93 that a likely attack on the U.S. Capitol was averted?

Remember when those attacks killed nearly 3,000 people on September 11, 2001, and has caused countless deaths afterward due to 9/11-related illness?
