Trump’s Renewed Greenland Proposal President Donald Trump has again pressed a bid to acquire Greenland, citing a map that links his ambition to a century‑long pattern of American territorial expansion; the article notes Greenland’s status as a Danish autonomous region and highlights Denmark’s warning that a U.S. invasion would terminate NATO membership, underscoring the diplomatic stakes involved [1].

Greenland’s Political Status Within NATO Greenland remains an autonomous territory under Denmark, which is a core NATO member; any shift in sovereignty would therefore have broad alliance ramifications, and Denmark explicitly warned that a U.S. invasion would end its NATO participation, reflecting the region’s strategic sensitivity [1].

Historical Precedent of U.S. Territorial Expansion The piece outlines 19th‑century acquisitions—including the 1867 Alaska Purchase, the Louisiana Purchase, Florida, the Gadsden Purchase, Texas annexation, Hawaii, and the Oregon Territory—that collectively defined modern U.S. borders, using the map to illustrate how each deal expanded American reach across continents [1].

Strategic Implications of Arctic Acquisition The Alaska Purchase historically extended U.S. influence into the Pacific, and a Greenland acquisition would similarly broaden American presence in the Arctic, potentially heightening geopolitical competition with Russia and China while provoking NATO‑related security concerns [1].
