I still see major obstacles to indyref 2: Scotland would have to join the Euro and Schengen, and build a border with England. That's choosing work over family and I bet Sturgeon doesn't underestimate the risk of a 2nd (and final) "stay".
Also: borders are sacred in Europe. States don't want to split/remodel per a 60 years old tradition.
There is a very strong case for indy Scotland (and i support it) but I admire that Sturgeon is smart enough to try and get the best of all possible outcomes.
