>If tomorrow morning Friesland decides by majority vote it wants to be independent of the rest of NL I'd be perfectly ok with that. That is a easy postition for the Netherlands to take because it has very little security against invasion even now before Friesland secedes, given its location in which there is little in the way of mountains, rivers or seas between it and countries more powerful than it. (More powerful if only because of their greater size: I'm not claiming that the Dutch are bad at fighting). But it would be foolish for Australians to allow a large chunk of Australia to secede or for the Japanese to allow part of Japan to secede because the way it is now, both countries enjoy a very favorable security situation in which any invader would need to cross an ocean or at least a wide channel even to begin an invasion. If Japan split into two, then one of the two new countries might invite in the military of a larger power with the result that the other new country is in a vastly more precarious security situation than it was before the split into 2 countries. The Mongols attempted a massive invasion of Japan, but the invasion was foiled by stormy weather while the Mongols were trying to cross the wide channel. If there were two polities in Japan at the time, the Mongols could have offer to protect one polity from the other one, and if their offer had been accepted, they could have moved their forces to Japan at their leisure, and would not have needed to risk an operation in which all their forces try to cross a sea as quickly as possible ready to fight as soon as they get to the other side. Because of their separation from other countries by large bodies of water, Australian and Japan have been invaded or occupied only once in the last 2000 years (Australia when Europeans arrived and Japan after WWII) whereas during those 2000 years, the Netherlands has been invaded many times (with the occupation or annexation of the Netherlands by Spain having proved particularly painful). Again: the Netherlands is not giving up much in the way of security advantages by allowing parts of itself to secede, but not all countries are in a similar situation.
