Reading is fundamental. Tell me, where in this century did the US engage in stuffing large numbers of Americans into a foreign country, then making a territorial claim and taking that area by armed force?
We are not talking about the typical flow of defensive moves between adversarial nations in order to maintain the status quo. This demonstrably goes beyond that.
Somebody hasn't read their history books at all.
That's literally how the USA expanded, move folks in to places where others are, wait for trouble, use that as an excuse to send in the army an annex it and repeat.
Russia is doing to the Ukraine what the USA did to Mexico.
Do you think you have to use only your own people to play the stuffing and destabilizing game?
You think it has to be just people you move in and that you can't just do it with corporations move them in, then invade to "protect American assets"?
Have you ever looked at the entire history of the USA and their dealings with central and south America and why the term "banana republic" was coined?
Oh and little island countries, or small countries, well there is some USA nationals there and we say they feel threatened so... send in the army and regime change invasion, leave once we have a new puppet installed.
The British were doing the population stuffing and "assets" stuffing things long ago all around the world, the USA learned a thing or two from them.
The entire history of Europe is kind of this. Folks think modern countries are always as they have been, but some 100 to 200 years ago many countries you think about in Europe weren't as they are, neither was the middle east.
What about when the Polish claimed much of the "Ukraine" as part of Poland for a good long time?
Perhaps you forget also the last time Haiti tried to get rid of a corrupt government and have some folks take over that cared about the locals... oh we invaded on the double... can't have a non puppet running the show.
If you take a break from the comfortable Jingoism and go look at things from the other side and see the world for what it really is, you come to understand we are not on the side of the angels and neither is anyone else. It's a race to the bottom of who is the least worst of the rotters.
This isn't new, you can go all the way back thousands of years and it's the same story just different ways of killing each other.
