The U.S. began a buildup of its military presence in the region to push away a possible planned campaign by Iran and its non-state allies to attack American forces and interests in the Persian Gulf and Iraq.

This followed a rise in political tensions between the two countries during the Trump administration, which included the withdrawal of the U.S. from the Joint Comprehensive Plan of Action (JCPOA), creation of new sanctions against Iran, and the designation of the Islamic Revolutionary Guard Corps (IRGC) as a terrorist organization.

In response, Iran made the United States Central Command as a Terrorist organization.
