short and simply explain how 9 - 11 waas an inside job

The idea that 9/11 was an "inside job" suggests that the U.S. government or certain officials orchestrated or allowed the attacks to happen for political gains, such as justifying wars or expanding government powers. Proponents of this theory point to perceived inconsistencies in the official accounts, alleged prior knowledge of the attacks, and the quick response to implement security measures as evidence. However, this theory is widely disputed and rejected by official investigations and experts who attribute the attacks to the terrorist group al-Qaeda.
