What is the value of NATO?

The background of the question 'What is the value of NATO?' lies in the existence and purpose of the North Atlantic Treaty Organization. NATO is an intergovernmental military alliance established in 1949 to counter the military power of the USSR and prevent the revival of nationalist militarism. It currently has 28 member states across the US, Canada, and Europe. The alliance aims to maintain peace in Europe, provide protection for economic recovery after World War II, and counterbalance the power of the Warsaw Treaty Organization. However, it also faces criticisms such as high military spending and interference in the internal affairs of other countries.
