Hi Granny23. Yes, it is indeed a global supply chain which relies on being able to cross borders without tariff or, in the cross - UK instance, currency exchange transactions. This level of ease would be greatly threatened in a situation where Scotland was a foreign trading nation, part of a different trading bloc, to the remainder of the UK and trading with a different currency - even if it is called the Pound. It simply doesn't make sense.
And, durhamjen, as someone once said, it's the economy, stupid. Without a thriving, viable economy anything else is just hyperbole. I wish the UK had remained within the EU. But given that it hasn't, I see no sense in Scotland cutting off its nose to spite its face and turning its back on its strongest ally and market. If there is to be another referendum, it makes no sense to vote against the last 300 years. It makes every sense to vote for the next 300 years and we must each determine in our own minds, having considered all the evidence, where the stronger future lies. I have no doubt that our greatest chance is that it lies within the UK. People who have given their lives and souls to "Scottish Independence" hold to it like a religion. But faith is not enough in today's world. You need reality.
