Answer:
Multilateral action is always better than unilateral, but that is not always possible. The United States, for instance, invaded Iraq with assistance from other countries. Unilateral action is taken if a country feels its national security interests must be protected at all costs. Even if one's actions are not supported by others, action must be taken.
Explanation: Because the world is becoming more global, it is necessary to align one's self with other nations in order to achieve certain goals.
