 
                Trump has been talking about Greenland and even Canada for very strategic reasons!
The most remote US military base is likely Pituffik Space Base in northwest Greenland, a strategically important installation in the Arctic, known for its role in missile detection and space domain monitoring. It is a Space Force base. Remember Trump created the Space Force? It was formerly called Thule Air Base and was under Air Force control.
Yes, the Space Force still somewhat operates as Air Force. The United States Space Force (USSF), established in December 2019, is the newest branch of the US military and the sixth US armed force. It's part of the Department of Defense and the Department of the Air Force.
Ask any Marine vet they get checks from the Navy. The U.S. Marine Corps and the U.S. Navy are distinct branches of the U.S. Armed Forces, both under the Department of the Navy, with the Marines specializing in amphibious and rapid-reaction combat operations, while the Navy focuses on naval operations and maritime security.
And yes, China has been taking over the Panama Canal while the USA paid for it and built it, and stupid Jimmy Carter gave it away. Carter also created the US Deoartment of Education. China is also occupying in the Arctic with help of Russia. China themselves have no coast up there. We do only through this base and Alaska. The Russian Empire sold the USA Alaska in 1867 for $72 million.
