Question

Answer 1

A) If one country is being threatened by another country, the U.S. will get involved.

NATO's collective defense ideology, as outlined in Article 5 of the North Atlantic Treaty, states that an armed attack against one or more members is considered an attack against all members. This means that if a NATO member is threatened or attacked, the U.S. and other member countries are obligated to respond, which often results in military involvement.
