@BillRM,
Laying claim to neutral status was a very deliberate and clear choice, and put them on the back of a running tiger.
They wagered that the Allies and the Axis would raise the value of their being a neutral country above whatever specific value they could provide as an "ally."
They were playing both sides against the middle, but it wasn't sustainable because eventually one of the two opponents were bound to find a need for Switzerland that had nothing to do with their neutrality. This was even more assured by the fact that the Swiss sought to profit on the fact that there was a war going on outside of their borders.
The matter of the ball-bearings followed their declaration of neutrality, and demonstrates the peril of the neutrality strategy.
It's a pretty good bet that that if they hadn't sold the ball-bearings to Germany, it would have invaded their country, but obviously the sale of these parts to their enemy didn't prompt the Allies to punish Switzerland. The Swiss were lucky.
I doubt that the Swiss ever though their neutrality would play out perfectly, but they bet on it as the best option for their nation. In retrospect, it was a pretty good bet, but it could easily have been otherwise...which of course is the essence of betting.
National neutrality is not a position based on morality, it is a strategy; the strategy of the merchant.
It worked for the Swiss in WWII but it might not the next time.
Better, I think, to take a stand than to hide in the shadows and hope that the warriors don't notice you.
