realistically the geographical distance is why it wont happen. but besides that, i would expect a sort of annexation jubilee where all of these potential states join together to allow for a political balancing that makes everyone happy, allowing a 2/3 majority to come about.  itd be cool to have you guys join us, though. you guys and norway are the two european nations that seem to not have that continental stick up your ass.  finland too, but they are a bit different i think.
