European security refers to the measures and strategies that European countries implement to protect their nations and citizens from various threats, including military aggression, terrorism, and cyberattacks. This involves cooperation among countries through organizations like the European Union (EU) and NATO (North Atlantic Treaty Organization), which work together to enhance collective defense and promote stability in the region. In recent years, European security has been influenced by challenges such as the Russia-Ukraine conflict and rising tensions in the Balkans. These events have prompted European nations to strengthen their military capabilities and increase collaboration on intelligence sharing and crisis management to ensure a safer environment for all member states.
