If you DON'T understand why would a PANGERMANIC nationalist want to include Switzerland into his dream Gross Deutschland then you really don't know a thing.
I understand that word PANGERMANIC, I just don't understand why it has anything to do with Hitler and his strategic decisions. He thought it's his obligation to abolish Treaty of V. which he did.
But as a person with somewhat low historic knowledge, I definitely can't know how WWI and pre WWII Germans viewed Switzerland folk. With Austrians it was simple, they are orderly, German speaking, have long term historical ties with Germany, and quite intermixed already, they are nearly Germans. Switz are these jolly folks who can cause ear ringing when they shout. It's probably best leave them to theirs devices. Coincidentally while UK were considered basically Saxons, German made no intent to conquering UK, and planned to have long permanent alliance with UK even after conquering Europe. Few years ago there was a detailed study of relationships between Switzerland and Germans during WWII, and before. Paradox might like to read it before they'd make another blunder.
