THE SHORT AND MEDIUMTERM IMPACT OF AL QA’IDA ISLAMIST’S ATTACKS ON THE U.S.A., SINCE SEPTEMBER 11, 2001

September 11, 2001, when Islamists affiliated with the terrorist organization Al Qaeda attacked iconic buildings in the United States, marked a turning point in recent human history. The impact of these attacks goes far beyond other contemporary events, which triggered major geopolitical processes, such as the 1956 Suez Crisis or the 1979 Islamic Revolution in Iran. If initially humanity was in a state of shock, seeing how the superpower of the moment seems paralyzed by the aggression of a little-known enemy, later, security measures and geopolitical dynamics overturned not only the life of the Earth’s population until then, but also paradigms, strategic concepts, political behaviors. This article aims to analyze how the attack orchestrated by Salafist fanatics in Al Qaeda has transformed and continues to transform society and global geopolitical dynamics.
