Switzerland is protected from supposedly ever being invaded by convention. Scotland is not.
The moment Scotland became rich and independant, it would become a coveted asset in the eyes of Russia.
Canada might offer political support to Scotland to hold back Russia, but the USA would not. The USA won’t take a “protective interest” in Scotland unless Zionist interests get some clout there similar to what they hold in and over Switzerland. That’s probably not going to be forthcoming, so the same interest will be shown by the Americans as they showed in ‘protecting the Falklands’ when Argentina invaded.
Switzerland has always been a place strangely protected by supposedly every nation on Earth from ever being invaded (“The Convention”), but in the end it is just a militarily weak, geographically weaker landlocked nation no easier to defend than the former Yugoslavia. Add that to it being pretty much a moneybox for more international crooks than anyone can shake a stick at, and you begin to see just how much ‘international support’ Scotland would need to protect it simply from being annexed at the drop of a hat post-independance. 
If Hitler had tried it on (annex Switzerland) in WWII, he would have brought the rest of the world’s monied nations into the war against Germany. One might ask the question “At what stage of WWII did everyone participating REFER to it as being ‘WWII’?”
America didn’t give a toss about what Hitler was doing in Europe until one of Hitler’s axis buddies brought them into “the war”
Of course, all those fears pretty much materialised anyway with the Allies against the Axis, so invading Switzerland would, with hindsight, had been a much better strategy for the Nazis than Operation Barbarossa which began Germany’s WWII decline. 
A secure eastern front (by honouring the German-Russian non-aggression pact instead of breaking it!) would have left Hitler free to finish off the rest of western Europe unhindered - including what would have been the ‘jewel in the crown’ of Switzerland with all it’s bank vaults brimming with worldy assets.
If the rest of the world has lost it’s collective shirts in Switzerland, then there’s not going to be much international crowd with any financial clout left to bleat on against the invader either. Money talks after all, and those that have cornered the Swiss Banking System can re-write the future in their own image, re-creating all the Swiss institutions in their own image as they see fit. “Those in possession get to make all the rules” you might say. No nukes will get fired, because it’s still ‘mutually assured destruction’ as it has always been. The rest of the world has the choice of living poorer, or not living at all. The Victor gets to cop the lot.
So who’ll be next to try? - Russia, China, or an as-yet unformed alliance of Mediterranean, Latino, or South Asian nations?
