Rank the 20 most powerful countries in the world in 2021?

[Lord Halifax]

Japan is way too low on your list, Blue3.  Less powerful than Iran and North Korea?  LOL

It also doesn't make any sense to exclude Italy from your list, as it is still a top-10 economy.

But its chaotic and dysfunctional politics means it's unable to use that potentiel influence. E.g. Italy consistently ranks below Spain and sometimes even the Netherlands in studies of member countries' influence in the EU. Power isn't just about resources and capabilities, but your ability to use them.

we are still one of the top three naval powers

Do you base that on some study? Military Today rank you as 5th behind the US, Russia, China and Japan.

Isn't that just naval spending?

This is based on a study from 2019.

No, it's not based on spending.
