On September 10, 2001 Donald Rumsfeld announced that there was 2.3 TRILLION dollars "unaccounted" for in the Pentagon budget. That amount was 7x the ENTIRE Pentagon budget for the year.
Only the government could lose their ENTIRE budget SEVEN times in one year AND get away with it!
The next day, three hijacked planes, reportedly flying at approximately 2x beyond the structural limits of their flight speed at sea level, crashed into buildings destroying all the accounting records and there could be no further investigation.
These facts are NOT disputed among government officials.
