I reread it, can't believe I missed that sentence. I do agree with the A2050 that the regional aspect is working here in Europe and also in Asia, but that has I think also to do with the fact that the Megaregions as on the map are almost the same size as whole countries here. What's national here is regional on the East Coast.

Yeah, Turkey isn't going to get in because of it. But I can't complain about what we have now, the open borders system has increased the cross-national trade and cooperation and is a step closer to an EU that actually means something. How are you liking that massive book? I just started reading books on the geopolitical history and geography of Europe, too, but they are more academic than yours I'm certain.

I misunderstood what you tried to say, to me this seems mostly as a map to get regional thinking to a bigger audience than to say something about the subdivisions agriculture, mineral, manufacture etc. I thought you wanted to take this map and apply it to the subdivisions, which isn't really possible when there are too many differences between this overall map and the qualities of those subdivisions. An agricultural megaregion would look vastly different than this map.
