Re x and y.
Translate that into Trident for starters and you will see that it is not so simple.
And we'll protect your borders if you allow us to use Faslane. I'm not disagreeing with you that there will be some quid pro quo, I'm saying that the rUK are hardly likely to fund the building of what you haven't got.
Imagine the success a Con party would have at the next election if they turned round to rUK before Sept and said, "rUK taxes will fund the development of Scotland post independence." Its almost the political suicide the Cons would commit if they said lets totally privatise the National Health.
And if Scotland is so much more wealthy than rUK, as is being suggested, maybe it will be Scotland paying rUK for going its own way...
