Buy European

You're looking in the wrong place. Several EU members have far right leaders already, many more are moving right. The EU (and UK) are about 4 or 5 years behind the US. Don't confuse disagreement with Trump over Ukraine with meaningful ideological differences.

Ah yes, because the EU is a bastion of respecting human rights. Supporting genocide politically and financially is a great marker of that? 🙄

To exercise the amount of economic and military power to be a world super power you need centralized command, control and decision making. The EU won't be able to take on russia if each state is able to back out of the war, and a state isn't fully sovereign if it can't make it's own decisions on going to war.

Same with economic policy, if one state is able to opt out of the free movement of goods and people then the benefits of a single market are diminished, but if a country can't make it's own decisions on trade and immigration policies then they've relinquished some of there sovereignty.

Institutions like the EU already do some of this but it'll need to be a bit stronger to be on the level of the u.s. and China in terms of the central power it possesses. Doing so buts up against the euro-skeptic movement though, which holds the EU back.

I don't think the EU is the successor to all of those

The EU is definitively a world power or great power. The EU might rise to the level of superpower, which is where the US is.

Being a great power just means that you can exert influence over events on the world stage. Having a meaningful say in how international organizations are run, or the ability to influence conflicts outside of your direct realm of control.

The EU is not yet at a point where no power can take a meaningful action on the world stage without considering how the EU will react to that action, which is one of the defining criteria of a superpower.
Despite having burnt an enormous amount of soft power for no reason, the US still holds a position where they can't be disregarded. EU military spending patterns are changing because the US is changing it's stance on a conflict they aren't really involved in beyond a "superpowers are involved in everything" sense.

Being either type of power has benefits beyond what it gives to those in control. In general, the leverage is used to effectively bribe the populace of the power. Pushing international organizations to prefer vendors from your country, driving business to it. "Thank goodness that agricultural development program bought their equipment from us, we had a great year, our jobs are intact and we actually hired more people".
It also brings cheap goods preferentially.
The benefit to the people in control is that it simplifies distributing favors to the people who keep them there, which in part includes the general population. "I'll let you buy these tractors from me on the condition you sell me every mango in your country for a decade. I'll even give you the tractor money back over the course of the decade. If you don't accept the deal no one will make a different one with you for fear of me not renewing my contract with them".

You don't have to have our broken internal culture to be a power. That only makes it so people take our position for granted.
