LONDON — If Scots vote Thursday to sever their 307-year-old union with England, the repercussions of a split may be felt globally — from entrenched economic and defense treaties to a flag that will go from three colors to two.
Would an independent Scotland still be a member of the European Union and NATO? What currency would it use? How will its oil wealth be divided up? Will its social welfare protections be better or worse off? Will there be an exodus of business down south? Will Scots living in England need to apply for visas? Will jobs be lost?
Unionists and pro-independence backers continue to answer these questions in different ways, and some of the institutions directly concerned have preferred not to answer them at all.
