Armed Force

This pop-up case is part of the series: Tools of Foreign Policy


Armed force encompasses any use or threat of violence to influence a situation. It is a powerful tool of foreign policy, but one that carries immense costs and risks. In this hypothetical scenario, the United States needs to decide whether armed force is the best tool to influence the trajectory of a crisis and, if so, how to deploy its military to achieve its objectives while minimizing risks.


First, cover the fundamentals of this foreign policy tool with World101's lesson, What Is Armed Force? Then, put these principles into practice with Model Diplomacy's hypothetical decision point below.

Decision Point (Hypothetical)

Pugnaria has descended into a civil war after rebel groups challenged its autocratic government. The United States has long opposed the current government of Pugnaria and suspects it has harbored or aided anti-American terrorist groups in the past. The government is brutally quelling the rebellion. Without outside help, analysts fear the conflict could lead to tens of thousands of civilian deaths and spark a humanitarian crisis. The president has convened the National Security Council (NSC) to discuss whether military intervention is appropriate and, if so, what form and level of support they will provide and for how long.

NSC members should consider the following policy options:

  • Mount a military intervention, striking Pugnarian government targets and supporting rebels as they attempt to overthrow the government. This could lead to a pro-U.S. government being installed by the rebels, but carries a heavy cost, risks U.S. lives, and could lead to an extended and controversial commitment if the conflict cannot be resolved quickly.

  • Send arms to the rebels and provide training and intelligence support. This option is cheaper than a military intervention and does not put U.S. lives at risk. However, the rebels, even with U.S. support, are not as capable as the U.S. military and their chances of success are lower.

  • Pursue nonviolent options. The NSC could turn to other tools, such as sanctions and diplomacy, to secure a ceasefire. If successful, this option could avoid a long and costly conflict and keep U.S. forces entirely out of harm’s way. However, other policy tools could well be insufficient to address the crisis, opening the United States to criticism for inaction.

U.S. politicians have raised alarm that TikTok, a popular video-sharing social media app owned by the Chinese company, threatens U.S. national security. Should the United States impose a ban on TikTok to safeguard citizens’ data and the country’s security?

In 2013, reports emerged that Syria’s President Bashar al-Assad had deployed chemical gas as a weapon in Ghouta, Syria, during the country’s ongoing civil war. Months prior, U.S. President Barack Obama had referred to this type of attack as a “red line” that, if crossed, would move the United States to act militarily. The United States now had a choice: whether to uphold its word and respond with military action at the risk of escalating a violent conflict.
