So.. an empire has to threaten to put a whole country in jail before it can be an empire? Does it dig up the land and physically put it in prison? Only the leaders? Every single person?

That meets no definition of empire I've ever heard of, and I'm not sure what you are even arguing anymore. Are you just trying to find something to be right about?

Come on!

Look outside your idealogical bubble for a couple of minutes, and think about what your point is.

If your point is that the US isn't an empire, then sure - I think everyone will agree it was never the same as the Roman empire or the British Empire.

But the post cold-war US was something, which involved it obtaining a lot of power in many forms. Some of this power was financial and was based on the US dollar being the reserve currency, and even the US's enemies had little choice but to concede to that power.

When the OP said that this is the end of the US's empire, that is what they meant. Think about that - if you disagree, then fine. There are reasons to think they could be wrong (this has been tried before and didn't work then).

But claiming the US is not an empire because it didn't collect taxes (!) as though that somehow invalidates the argument is just wrong.
