The real reason Trump posted he wanted to send a hospital ship to Greenland, most likely is the fact that Danish Joint Arctic Command just evacuated a US Navy Sailor from a US submarine near Greenland, because the sailor was in need of acute medical attention.

Trump might have been asked to thank Denmark for this important help, but instead Trump came up with this weird distraction to hand to Fox News that the US is the one helping Denmark with a hospital ship, as if we did not have hospitals.
