President Donald Trump signed an executive order on Tuesday that creates a national security guarantee with Qatar, saying that any armed attack on Qatar will be considered a threat to the U.S.
The order is sweeping, saying that "the United States shall regard any armed attack on the territory, sovereignty, or critical infrastructure of the State of Qatar as a threat to the peace and security of the United States."
In the event of an attack, the order says that the U.S. will "take all lawful and appropriate measures — including diplomatic, economic, and, if necessary, military — to defend the interests of the United States and of the State of Qatar and to restore peace and stability."
The order directs the U.S. secretary of state, defense secretary and the director of national intelligence to make a contingency plan with Qatari officials "to ensure a rapid and coordinated response to any foreign aggression against the State of Qatar."
The order comes after an Israeli strike on Qatari soil last month. After Israel's strike on Qatar, the White House said that Trump spoke to the Qatari emir and prime minister and assured them that such a thing will not happen again on their soil.
Iran also fired missiles at a U.S. military base inside Qatar in June.
