Typical simple-minded paleo/libertoid foreign policy analysis.
Harry Browne and the rest of you libertoids just love the example of Switzerland and the Nazi's. Minding there own business, and everyone armed to boot.
So how do you explain the failure of the Nazis to invade Sweden during World War II? Sweden was a major source of iron ore to Germanany. Without Swedish iron ore, the German war machine would have ground to a halt.
And yet, somehow, the Germans never felt the need to invade Sweden either. Why? Because as long as the bullion kept coming, the Swedes were happy to send the ore.
Just like Switzerland. As long as the Nazis got what they wanted, it wasn't worth invading.
Explain what need there was to invade them. Have you been to Sweden? I have. Have you been to Finland? I have. Have you been to any air museums in Finland or Sweden. I suppose you can explain why the Majority of old flying ships there have swastika's painted on them.
The Nazi's wanted Switzerland badly. Hitler especially. Strategically, it's a gem in Europe. Hitler's generals convinced him that it would be insanity to try.
It is clear that the money was of no consequence in their decision. There was a tremendous treasure to be had but the price was too great.
