What was a reason for the U.S. involvement in Libya during the Arab Spring?

The involvement of the U.S. in Libya during the Arab Spring primarily stemmed from humanitarian considerations and the need to protect civilians. The imposition of a no-fly zone over Libya was part of a broader strategy to limit the Libyan government’s ability to attack its own citizens. The United Nations authorized such a no-fly zone to prevent aerial assaults by Muammar Qaddafi's forces, which were targeting opposition groups and civilians. This action was seen as necessary to protect lives and support the uprising against Qaddafi's regime, reflecting a commitment to humanitarian intervention in the context of emerging democratic movements in the region.

While other options may relate to different aspects of U.S. foreign policy, they do not directly align with the immediate objective of the no-fly zone, which was specifically aimed at limiting violence against civilians and providing a safer environment for those engaged in the revolt against Qaddafi.
