Fair enough. I just googled the meaning of “hegemony” and it said “leadership or dominance, especially by one state or social group over others”. So what I mean is that Europe doesn’t necessarily need to be dominant in the world, but it should be able to stand up for itself.

we literally need to get to a single-world-government as soon as possible to secure our survival as a species

I’ve thought about that a little bit. Perhaps such a government could help resolve disputes. It could perhaps prevent terrible wars like those in Gaza, Ukraine, and Sudan. Maybe a single world government will happen at some point, in the distant future.
