Why do you think that Austria and Switzerland don't fear Nato? Both countries are surrounded by Nato countries. And yet they aren't "weakened by nato border countries". Why is Russia?
Because they do not have 4,000+ bombs. They are nonentities as far as muscle power goes. Russian, Chinese and N. Korean bombs and missiles
threaten US dominance. That is what US is concerned about. If it was not for them, Trump would have declared himself the Emperor of the World.
You are very "American centric". I actually think that the US is in decline. America is certainty moving away from Europe. The reason that Austria and Switzerland aren't threatened by Nato is that they have no intensions of invading any NATO country. They want to trade with the other NATO countries. They aren't led by maniacal dictator who wants to conquer land to establish his destiny.
The U.S., despite so many who wish for it to be, is not in economic decline nor is its influence around the globe.
As for Austria, whatever. They're buffered from Russia by four different nations, so their concerns are nowhere near as great as the countries that directly border Russia.
And fuck Switzerland. Its geography makes it worthless in terms of hostile military occupation, which, unlike every other European nation allows it to insulate itself from the real problems in Europe all while patting itself on the back for its bullshit high-minded neutrality. It's the money laundering capital of the western world, and its hands are as bloody as any other nation with respect to turning away Jews during the Holocaust.
Oh, but they have yodeling, elaborately decorate their cows, and have a famous Disneyland ride named after a geographical feature! Yay Switzerland!
