Nicola Sturgeon is leading Scotland down a very dangerous path with another referendum; with the sole selfish purpose of becoming a supposed national hero.
Much like the Brexit campaign, there is no real substance in what she says - it is all rhetoric. "We can do this, we can do that" and that's fine, but it's hardly a solid base to break into economic independence in such uncertain times. EU member states are already saying Scotland will be unwelcome in the EU, Spain in particular due to tensions with Catalonia. What happens then? They will presumably be stripped of the pound so would have to have their own currency and create their own trade deals, with England likely their biggest importer / exporter as they'd need to get a deal in place quickly.
Just like in the last referendum, i'm sure the Scottish voters will realise that rhetoric is not enough. If Nicola Sturgeon can put in place a bona fide plan with agreements in place as to how Scotland will survive as an independent state, then good on them and if they vote to leave then good luck to them. However, as I'm sure it will be, she will be spouting rhetoric right the way through and I sincerely hope the Scots can see through it and not leave the UK on an emotional decision, but one based on a solid foundation to give themselves the best chance.
