Finally, at Lisbon we can continue to forge the partnerships beyond NATO that help make our alliance a pillar of global security. We must keep the door open to European democracies that meet the standards of NATO membership. We must deepen cooperation with organizations that complement NATO strengths, such as the European Union, the United Nations and the Organization for Security and Cooperation in Europe. And with the attendance of President Dmitri Medvedev at the NATO-Russia Council summit, we can resume practical cooperation between NATO and Russia that benefits both.

For just as the United States and Russia have reset our relationship, so too can NATO and Russia. In Lisbon we can make it clear that NATO sees Russia as a partner, not an adversary. We can deepen our cooperation on Afghanistan, counter-narcotics and 21st century security challenges — from the spread of nuclear weapons to the spread of violent extremism. And by moving ahead with cooperation on missile defense, we can turn a source of past tension into a source of cooperation against a shared threat.
