The 2019 Persian Gulf crisis is an escalation of military tensions between Iran and the United States following the deployment of substantial military assets to the Persian Gulf by President Donald Trump due to alleged intelligence suggesting a planned "campaign" by Iran and allies against US forces and interests in the Persian Gulf and Iraq. This followed a rise in political tensions between the two countries during the Presidency of Donald Trump, which included the withdrawal of the United States from the nuclear deal, the imposition of new sanctions against Iran, and the American unprecedented designation of the IRGC as a terrorist organization.
