I have serious reservations concerning this "acquiring" Greenland, Canada, or even the canal.
First is Greenland. What do we "need" Greenland for? I don't see how it's a strategic land mass, and this suggestion of stripping it's minerals just hits a raw spot. And if we use military action, how is that any different than Putin going after Ukraine? Greenland is a possession of Denmark, and this whole idea is suggesting that we'll be declaring war on Denmark? I THINK NOT!! If we don't honor the sovereignty of other nations, how are we to expect other nations to honor our sovereignty?
The same goes for Canada. Honor their independence and sovereignty, and leave them alone. If "we" want a "northwest passage", BUY the right-of-way, don't try to take it.
As for the canal, I can see some of the logic, BUT........if we go back on our own treaties, how can ANYONE have any trust in the U.S. at all, at any time? OK....maybe China is influencing goings-on in Panama, but to "take" the canal, by any means, is again, just as bad as Putin's actions against Ukraine. The better solution is to STOP BUYING CHINA'S CRAP! They'll no longer have much need for the canal, and maybe some of that industry will come back home and generate needed jobs FOR AMERICANS. Besides, it would be terrible business for Panama to even allow us to have it back......they would be extremely foolish to let go of that cash cow.
I'm starting to have "buyer's remorse" over some of this, as his verbal actions are leaning just a bit extreme. We have (collectively) berated other counties for hostile actions against their neighbors, and even their not-so-neighbors.....how about we live by our own words and tactics?
