The Effects of U.S. Military Support on Conflict

The Effects of U.S. Military Support on Conflict


The RAND Corporation published a report analyzing the impact of U.S. troop presence and/or military assistance on intrastate and interstate conflict.

In the News:

  • “Overall U.S. military assistance [in intrastate conflict] is positively associated with an increased risk of anti-regime activities and greater levels of state repression by incumbent governments.”
  • “U.S. military assistance, much of which has historically been in the Middle East, may overall be associated with a greater likelihood of repression or domestic instability”
  • U.S. troop presence is associated with a lower likelihood of interstate war but increases the likelihood of lower and higher intensity militarized disputes.
  • No observed relationship between U.S. military troops presence and intrastate conflict, but positive association observed between military assistance and anti-regime activities and state oppression.

Peace Science Insights:

  • U.S. military support to another country increases the chance of attacks from terror organizations from that country.
  • 95% of all suicide attacks are conducted to encourage foreign troops to leave the occupied country.
  • Depending on their relevance to U.S. foreign policy, U.S. troop presence can lower human rights levels in a host country.
