Please substantiate.

you only have to look around you

I don't see many US products. From mobile phones through efficient electric and car motors, vehicles, kitchen appliances, power plants, etc., I see products of European innovation.

Who speaks of "vassaldom to the USA,"?

For example, Brzezinski:

"To put it in a terminology that harkens back to a more brutal age of ancient empires," he writes, "the three grand imperatives of imperial geostrategy are to prevent collusion and maintain security dependence among the vassals, to keep tributaries pliant and protected, and to keep the barbarians from coming together."

But in what sense do you think European countries' relationship with the US is NOT vassaldom? When has the US bent to more than symbolic European demands in NATO, as opposed to the other way around? I ask again, what benefit does Europe draw from an 'alliance'?
