Many conspiracy theories have been presented concerning the September 11, 2001 attacks, many of them claiming that President George W. Bush and individuals in his administration knew about the attacks beforehand
The twin towers were still burning when the first conspiracy theories began with traders laying an 'extraordinary' amount of put options on United Airlines and American Airlines stocks, the same airlines that were hijacked during the attacks.
The US Air Defense was told to stand down, the World Trade Center collapse appeared similar to a controlled demolition with some witnesses hearing explosions inside the building as they attempted to escape, the impact holes in the Pentagon were much smaller than a commercial American Airlines plane would make.
The conspirators question how the paper passports of the terrorists survived the explosions which destroyed buildings and why 4,000 Jewish employees at the WTC took the day off from work on September 11, 2001.
The most agreed upon theory is that the President set it up as a justification to go on a war frenzy in the Middle East to remove Saddam Hussein from Iraq, a conspiracy which gained further traction when it was shown that the President had to defend his extremely tenuous links between Saddam and the 9/11 attack while all of the terrorists were Saudi Arabian.
