Trump's 'Monroe Doctrine' Tweet Pinned to U.S. State Department Account

A pinned post on the official U.S. State Department social media account is drawing global attention. It quotes President Donald Trump: "This is OUR Hemisphere, and President Trump will not allow our security to be threatened." The statement directly references the Monroe Doctrine. This is a 200-year-old U.S. foreign policy principle. It warned European powers against new colonization in the Americas. Modern presidents have rarely invoked the doctrine so directly. The decision to feature it on the State Department's official channel is unusual. Diplomats typically use these accounts for formal policy announcements. Analysts say the move signals a clear shift. It emphasizes unilateral power and a regional sphere of influence. Allies and rivals are now watching to see how this "Trump Doctrine" is applied.
