Cause he knows everything he needs to know about the complexity of such a debate. His ancestry didn't want to be Spanish and they didn't vote, they went to war against Spain in the name of identity so frankly anyone sitting in Brussels right now should behave like grownups, be seated, relaxed and watch. The Scott will vote and they will make a decision for themselves and nobody else, everybody else should mind their own business, regardless of the decision the Scott will make, the following day the competition on the world stage will be exactly the same it is today and the price of oil and gaz very little affected by the decision, more, the following day the Scott nation will still be a European nation and there will be plenty to do with Scotland regardless of its government status. Only those who share dear interests and have shared a common history in peace and war times with Scotland today should and can have feelings and arguments about the decision the Scott are about to make, that is England and Wales but even so they probably should make full use of the best wiseness experience can provide given there will be days, months and years after the decision whatever that is where the best relations will be needed to continue to grow efficiently all the european economies.
