After the manifestation of mass terrorism at the 9/11 attack against the United States of America and the following terrorist assaults in Morocco, Saudi Arabia, Turkey and Spain, the provision of security to the 2004 Olympic Games came to be discussed in a new light. In Greece, in particular, responding to such threats became a matter of national defense. Although there was no specific intelligence indicating a specific terrorist threat to the Athens Olympic Games of 2004, the countering of such an eventuality gained prominence. Since it was widely assumed that this required the decisive engagement of military power, the Hellenic Armed Forces (HAF) planned, in every detail, the application of military countermeasures against any potential terrorist threat from the air, the ground and the sea.
