"This is an action plan, which sets out clearly the concrete steps NATO will take. This action plan will put in place an alliance that is more effective, more engaged and more efficient than ever before," stressed the NATO secretary general, as he presented the new Strategic Concept in Lisbon.
If the Cold War is well and truly over, proliferation of nuclear weapons and ballistic missile, terrorism and cyber-attacks are posing a real and growing threat to the security of the alliance's member states.
"As long as nuclear weapons exist, NATO will remain a nuclear alliance," the strategy states. NATO therefore commits to maintain nuclear and conventional forces, but also to seek cooperation with Russia and other Euro-Atlantic partners to develop a ballistic missile defense shield.
As societies are becoming reliant on information technology, the alliance will work on developing its capacity to prevent, detect, defend against and recover from cyber-attacks.
NATO will focus on the fight against terrorism through better international cooperation and development of adequate military capabilities.
Following missions in Afghanistan and the Western Balkans, NATO leaders have also committed to prevent crises, manage conflicts and support reconstruction missions through enhanced cooperation with the United Nations and the European Union. NATO will also engage in conflict regions outside the alliance as instability could pose a threat to the security of the organization's territory and populations.
The new Strategic Concept also offers partner countries and organizations around the globe more opportunities for dialogue and cooperation in an effort to enhance international security.
NATO therefore wants to reinforce cooperation with Russia in areas of shared interests, including counter-narcotics, the fight against terrorism and international security. Cooperation with Russia will also be enhanced through the use of the NATO-Russia Council to its full potential.
"NATO poses no threat to Russia. On the contrary, we want to see a true strategic partnership between NATO and Russia," the document states.
The 2010 strategy also keeps the door firmly open to membership in NATO to European democracies as long as they assume the incumbent responsibilities and meet the accession standards.
Finally, the new Strategic Concept underlines the need to invest in appropriate areas and to undertake reforms towards a more effective, efficient and flexible alliance.
Rasmussen on Friday opened the meeting of NATO Heads of State and Government in Lisbon, stating that it will be one of the most important summits in the military bloc's history.
