Security and defence refer to the measures and strategies employed by nations to protect their citizens, territory, and interests from threats. This includes military forces, intelligence agencies, and law enforcement, which work together to prevent and respond to potential dangers, such as terrorism, cyberattacks, and armed conflicts. In addition to military capabilities, security and defence also encompass diplomatic efforts and international cooperation. Countries often engage in treaties and alliances, such as NATO, to enhance collective security and address global challenges. Effective security and defence strategies aim to maintain peace and stability while safeguarding national sovereignty.
