Despite NATO’s reaffirmed commitment to promote peace and security, Ms. Ann-Kristin Otto argues that member states’ divergent opinions on how to address threats, the specter of unrewarding military engagements, and crippling impacts of the international financial crisis pose serious challenges to the basis of international solidarity on which the organization depends. With many European nations cutting their defense budgets in light of austerity measures, will the United States adequately fill the funding gap to support NATO? Has NATO placed too much emphasis on “painting a portrait of success” in its military engagements rather than investing efforts in forging sustainable change? Should member nations officially determine what constitutes a threat in order to guide NATO’s intervention? Should NATO seek to address emerging security issues like cyber crime, energy security, or terrorism?
