> But this is obviously not true.
It is obviously true. The five permanent security council members are US, China, Russia, UK and France. US, China and Russia are obviously gigantic. UK is gigantic via its ties to Canada, Australia, NZ. After all the silly monarch of britain is the head of state of all these nations. And France has a gigantic empire still. Go check out their EEZ.
> but it’s not like Germany and Japan are powerful because of their landmass.
Germany and Japan aren't powerful. Powerful nations aren't occupied by a foreign power. Germany and Japan are extraordinarly weak. Their economic well being is entirely dependent on the generosity of another nation.
There is a reason why Germany and Japan tried to expand their territories in ww2. They failed and they have to live with the consequences.
> I think judging countries by their size is a mistake in rationality and people shouldn’t do that.
Sure. Landmass by itself isn't everything. As I said, you have to factor in population, quality of land, ports, neighbors, etc.
> It’s only silly people who look at Greenland on a Mercator map and think that they are powerful based on size.
You quoted "the larger and more populous countries tend to be the most powerful and influential."
Do you know what populous means? It's silly to quote something and not understand it.
