Time to throw in my 1 Taneda here. First off, there is no single thing that can prevent war. It is a natural occurrence between humans. Nothing can stop it for good.Originally Posted by themanhunt1234
Secondly, you know what happens when governments join together? GIANT IMPERIAL DICTATORSHIPS. Look at every large nation to grip the Western Hemisphere...Holy Britannian Empire, Oceania...
...well, you get the idea. A single government that controls the entire world is bound to become extremely corrupt and will destroy everything we know today.
Not to mention, if that happens, no Hetalia Axis Powers anymore, since the countries have all disappeared as independent.
