That is true, but it also goes well beyond that. Much of the "US Gov't behavior" is largely related to trashing and panicked frantic moves because the consequences of its prior and long tailed actions over decades has now not only started bearing rotten fruit, but a previous strategy of world domination through "globalism" has also turned against those who control the Wizard of the USA from behind the curtain.
On the face of it the Greenland situation makes no sense on a national security level regarding a non-existent, fabricated Chinese or Russian threat, nor related to the fantastical grift of the "Golden Dome" that is even more useless against what Russia has recently developed, than it was for things prior to about 3 years ago.
What we are looking at here (you can tell your children that you heard it here first) is a strategic move to essentially take Canada and all of the NA continent, and eventually all of the Americas. Yes, Canada, you are indeed in danger as well as Mexico. I don't see how it could be any other way in the face of current developments; remember Trumps USMCA, i.e., a de facto North American Union?
Biden stated that he wants the USA to have 300 million more "immigrants" before he let in about 15 million in 4 years. Annexing Canada is about 40M by the time we do it, Mexico would add another 150M plus however many people would flood into Mexico to become "Americans". That bring us to a total of around 550 million by the time the North American Union comes around. Perhaps if the UK joins, we will just call it Oceania already.
It does not address the fact that China has 1.4 billion and India another 1.4 billion, but it puts us in contention, especially as Europe has about 700 million by that time if/when the EU absorbs most of Europe.
That also doe not take into account the Wizard of the USA wanting to take over all of South America for positive control eventually… another ~480 million by that time, putting the American Union of Oceania at about 1 Billion, ±100M.
These are real tabletop calculations and how things are seen at the top and discussed amidst cocktails.
