Taking that literally, because we should pay attention: what does that mean?
This is just my first thought but there are places that will want to join us. For a while. AU? NZ? Canada? UK? CROWN-controlled in the past?
And places that should unite for cleansing, and then declare independence. Puerto Rico perhaps?
And IMO some that might not want to be acquired, but that SHOULD be acquired. Greenland? Legendary historic home base of the Nephilim and Rephaim? Trump did hint that we should "buy" Greenland ;-)
And what about all of those creepy Cabal trips to Antarctica? Seems to be a Satanist/NWO stronghold there? Pretty sure that cannot be allowed in the future....So that too. Especially that.
We don't want anyone that is not contiguous to the US land mass joining us. We also don't want anyone with no value to add and that does not have at least a common language and customs to join us. The first would be impossible to defend and a drain on our security resources. The later would be creating division in our country as it already is along the area of the southwest being invaded from Mexico.
The only possibility is from a few areas of Canada. The western coast of Canada would be good to add since it would tie Alaska to the mainland US, and is rich in natural resources. Plus we could get the Chinese and Muslims off our northern border.
