Indeed. I remember some years ago having an argument with Soapy Sam who said two things I thought were plain wrong. One was that the direction of travel is to states uniting, not to states breaking up. That's plainly wrong. At the turn of the 20th century there were about 50 independent states, whereas there are now about 200. So factually the direction of travel is to smaller states. We only have to look at Europe to see that.
The other was that he favoured "one world government" and that any fracturing of a state was a step away from that. I couldn't get my head around that.
I can see two ways to "one world government", and the way that's promoted by the idea that states should get larger and larger (presumably by conquest or subsuming their neighbours) until there's only one of them absolutely horrifies me. It sounds like perpetual warfare getting worse and worse as larger states clash as to who should subsume whom, until you have only two superpowers and then what happens? Sounds like an absolute dystopia.
The other way is for states which see no threat of force from their neighbours coming together to pool sovereignty at national level, so that in the end the higher tiers of government mainly relating to global trade, relationships between states and possibly currency are dealt with by the top-level governing body at a global level. Leaving the individual states to look after their own local affairs within this framework. I don't want to have to send a docket to Beijing if the street light outside my window is malfunctioning.
The fact is that the latter route to one world government, no matter how likely or unlikely you think it might be to succeed, is the only one that doesn't involve a series of escalating wars. And larger states breaking up into smaller ones isn't simply no impediment to the process, it positively facilitates it. Large superpower states are the enemy of a world where states that don't threaten each other are co-operating amicably. For the one-world government fans, you should be celebrating occasions where large, unweildy states which try to "punch above their weight" and in which significant groups of people feel disenfranchised break up into smaller, more peaceful units. Not decrying this process with cries of "but you're taking me further from one world government!" Nonsense. A benign form of one world government is brought closer by the formation of smaller states, not further away.
