Question

under nato, the united states, canada, and western european nations agreed to
negotiate a peace treaty with the soviet union.
reduce their military forces by equivalent amounts.
ask the united nations for permission to go to war.
defend each other against attacks by responding with force.

Explanation:

NATO (North Atlantic Treaty Organization) is a military alliance. Its core principle is collective defense. Article 5 of the NATO treaty states that an attack against one member is considered an attack against all members. This means members agree to defend each other by responding with force if one is attacked.

• Negotiating a peace treaty with the Soviet Union was not the main purpose of NATO. NATO was formed as a counter - balance to the Soviet Union's influence during the Cold War.
• Reducing military forces was not a founding agreement of NATO. NATO was more about collective security and maintaining a military presence for defense.
• While the UN has a role in international peace and security, NATO's agreement does not center around asking the UN for permission to go to war. Its focus is on the mutual defense among its members.

Answer:

defend each other against attacks by responding with force.
