What are today's security challenges?
Today, we face a much broader range of threats than in the past. To the east, Russia has become more assertive with the illegal annexation of Crimea and destabilization of eastern Ukraine, as well as its military build-up close to NATO’s borders. To the south, the security situation in the Middle East and Africa has deteriorated, causing loss of life, fueling large-scale migration flows and inspiring terrorist attacks. NATO is responding by reinforcing its deterrence and defence posture, as well as supporting international efforts to project stability and strengthen security outside NATO territory. We are also confronted with the spread of weapons of mass destruction, cyber attacks and threats to energy supplies as well as environmental challenges with security implications. These challenges are too big for any one country or organization to handle on its own, so NATO is working closely with its network of partners to help tackle them.
