Trump has now successfully trash talked, bullied and bluffed Europe into getting serious about rearming itself. However crude the tactics, it worked. If Europe follows through and becomes an asset to the US, he'll like it again.
That certainly is a positive but I'm not sure a US as compromised from an intelligence point of view as it is will be viewed as much of an asset in return.
Hint: Trump is bluffing about Canada and Greenland to put them on the back foot psychologically over trade issues in Canada's case, and over having a closer relationship strategically in the case of Greenland.
And now Canada is removing US products from sale, forming alliances elsewhere and public opinion towards the US is at an all-time low. Not sure how Denmark and Greenland are responding at the moment but I would guess not favourably.
If you've never traveled in the US, it's hard to appreciate how vast it is. New York state alone is the size of England, and Texas and France are about the same size. We really don't need additional territory.
Neither did Russia by that metric, so not entirely reassuring. Security, resources, etc. It's not all about acreage.
