NATO is a political-military alliance of 29 countries in Europe and North America. All Allies share fundamental values: individual liberty, democracy, and the rule of law.
NATO safeguards the freedom and security of its member countries through diplomatic and military means. The Alliance also works to tackle threats including terrorism, the spread of weapons of mass destruction, and cyber-attacks.
NATO members protect each other. The collective defence clause of NATO’s founding treaty means that an attack against one Ally is considered to be an attack against all Allies.
Member countries contribute to the cost of running NATO and implementing its policies and activities. The organisation is accountable to its member governments and their taxpayers.
