Not sure what countries need with a small number of (very expensive) stealth fighters. They're not needed to enforce one's airspace or check out wayward airliners. They're too few in number to stand up to a serious invasion... Isn't this why the F-5 and F-16 and their Euro counterparts were created, so as to have a larger number of effective fighters?
Stealth can be dealt with, particularly in small countries like Switzerland, by advances in multi-frequency radar (or other spectral areas). Defensive missiles and drones are way cheaper and there's still a lot other be said filling regions of space with chunks of metal.
