In defence of small nation states
Scotland may have a second referendum within three years, as many Remainers correctly predicted. If the British government makes a mess of Brexit, the Scots may be inclined to leave the sinking ship and rejoin the EU. If Britain succeeds in going it alone outside a larger federation and doesn't suffer a huge economic setback then perhaps the Scots might think they can do so too. I'm rather inclined to believe that neither the UK or the EU will necessarily be around as this century matures, and it won't be the economic or emotional catastrophe people imagine. Sad though it would be to see ane end of ane auld sang, Scotland would do fine as an independent nation. They gave the world Adam Smith, after all.
