In the post-World War II era, United States foreign policy has dealt with international conflicts in several ways. The correct options from your list include:
- It has used dollar diplomacy to influence the behavior of other countries.
- It has formed international coalitions when the use of military force is necessary.
- It has often acted on its own when the use of military force is necessary.
- It has often disregarded the United Nations when international conflicts arise.
The statement "It has avoided becoming involved in international conflicts" is not accurate as the U.S. has frequently engaged in global conflicts and interventions since WWII.
