Reuters reports that the United States and Denmark are close to reaching a potential agreement that could expand the U.S. military presence in Greenland and allow the island to support the U.S. "Golden Dome" missile defense system. The agreement would fall short of Donald Trump's previous ambitions to acquire Greenland, but both sides are also discussing measures to limit China's presence and influence on the island. The agreement could be announced within days or weeks, but the extent of Donald Trump's support for the deal is unclear.
