And an huge colonial empire ( europe/japan/korea )

The US isn’t a colonial empire.

The US is one of the biggest colonial empires in history.

Then it should be easy to provide an example of a US colony.

Nato countries, easy.

You can’t seriously believe that, come on.

You can’t seriously believe that nato countries are really indipendent. The USA choose single ministers from certain countries and prime minister needs usa approval.

Do you have evidence for this claim?

It is not official ( of course ) , but very well know. Very former high official have confirmed that ( not officially of course ). The secrecy of real usa status is notorious. See what happened to Assange…
