For the OP and many others, please try and keep up?!! [But thank you 'Elegran'!}. This topic has been discussed many times, in assorted media, since his "we must have Greenland" rattle-throwing outburst.
USA had bases in Greenland dating back to the days of the Cold War, and President Truman.
See Wiki for a full analysis en.wikipedia.org/wiki/Military_in_Greenland
Over time, USA largely ABANDONED its bases there, but the new 'deal' means that one or two will be reinstated -- in THAT respect, I suppose Chump could be seen to be correct, but as he's gaga and never got past the 'H' of a history book, he's now talking as if it's a wonderful new 'achievement'. The way of the imbecilic but self-praising Orange Baboon.
There IS a strong suspicion that the aspect of military bases is just a handy cover to explore Greenland's remote landscape, searching for handy new precious metals. Though surely a grasping, amoral carpetbagger and all-round scumbag of a PoTUS would never dream of such a pretence?!
In general terms, yes, Chump is ever more hopeless with speeches, especially those where he goes 'off the cuff'. Irrational, bombastic, a crook, fraud and pervert (anyone seen those oft-promised Epstein files?), he's made most of the planet much poorer, including his own public, as hopefully he'll discover on Nov 4th (the 'midterms' have all 435 Representatives being elected, plus part of the Senate, two thirds of State Governors and a mass of other officials).
Unfortunately if when Chump departs (sooner the better) there is still a Republican PoTUS, it's likely to be another grasping, amoral nitwit (Vance is trying hard to get into position). At least the Democrats do now have some plausible charismatic candidates coming along.
I've posted this before, but there are always new readers :- About 100 years ago, an American journalist & essayist called H L Mencken published a number of witty quotes, this one was really prophetic :- “As democracy is perfected, the office of President represents, more and more closely, the inner soul of the people. On some great and glorious day the plain folks of the land will reach their heart's desire at last and the White House will be adorned by a downright moron.”
