On 12 September 2001, Allies responded by invoking, for the first time in NATO’s history, Article 5 of the Washington Treaty, the Alliance’s collective defence mechanism. This decision was a powerful expression of transatlantic solidarity and unity - as was demonstrated by Alliance operations in the air over the United States and in the Mediterranean Sea.
NATO and our partner nations from across the world can be proud of what we have achieved, individually and collectively, to reduce the threat of terrorism. In Afghanistan, Allies and partners have continued to display the strength and resolve needed to defeat terrorism, including by training local forces to fight terrorism themselves.
Our actions demonstrate that the spirit of solidarity today reaches beyond our Atlantic Alliance. They highlight the resilience of our communities and of our fundamental values in the face of terrorism, which continues to pose a direct threat to the security of our citizens, and to international stability and prosperity more broadly.
Vigilance, prevention, resilience and commitment to our fundamental values remain our best response. We will continue to fight the scourge of terrorism in accordance with international law and the principles of the United Nations Charter. NATO is determined to fight terrorism, drawing on its unique tools, capabilities and capacities. Cooperating with partner nations and other international organisations will further strengthen our ability to combat terrorism effectively. In light of the evolving terrorism threat, Heads of State and Government will review NATO’s approach to counter terrorism at the 2012 NATO Summit in Chicago.
We honour all victims of terrorism through our enduring commitment to safeguard peace and the freedom and security of our citizens.
