There were about 20 months left before September 11 when two American agents obtained information considered crucial by various counter-terrorism figures, who believe this discovery could have altered the course of the terrorist attacks.
The information never reached the FBI, which represents a significant failure in intelligence sharing between American security agencies. This omitted alert constitutes one of the most problematic moments in data communication between US intelligence services before the attacks.
The secret document contained details that, according to specialists in the field, could have allowed American authorities to take preventive measures and possibly prevent the attacks that would occur in September 2001.
The revelation of this incident raises questions about the effectiveness of information sharing systems between US intelligence agencies and about what could have been done differently to prevent the tragedy that killed nearly three thousand people.
