Over are the days of LGBT and Black Lives Matter flags being flown at foreign U.S. embassies.

According to The Washington Free Beacon, which obtained a copy of the State Department order signed by Secretary of State Marco Rubio, U.S. embassies will be required to enforce a "one flag" policy worldwide.

This means that only the American flag can be flown, while any other type of flag is banned.

"Starting immediately, only the United States of America flag is authorized to be flown or displayed at U.S. facilities, both domestic and abroad, and featured in U.S. government content," the order states.

"The flag of the United States of America united all Americans under the universal principles of justice, liberty, and democracy."

"These values, which are the bedrock of our great country, are shared by all American citizens, past and present."

Any employee found violating the new policy will "face disciplinary action, including termination of employment or contract, or reassignment to their home agency."

The only exception to the rule are the Prisoner of War/Missing in Action (POW/MIA) emblem and the Wrongful Detainees Flag.

"The U.S. flag is a powerful symbol of pride and it is fitting and respectful that only the U.S. flag be flown or displayed at U.S. facilities, both domestically and abroad," the memo.

Over recent years, several U.S. embassies have flown flags promoting left-wing political ideas alongside the traditional Stars and Stripes with the full endorsement of the Biden administration.

The most notable of these embassies was in Brazil, which shamelessly hoisted the flag of the Marxist terror group Black Lives Matter.

"Today, we raise this flag to reiterate the importance of black lives around the world," said the Chargé d'Affaires of the U.S. Embassy and Consulates, Douglas Koneff, at the time.

"The United States is committed to continuing this fight and collaborating with any others who wish to do the same."
