> Maybe some trust will be restored in a generations time, but there is no going back to the post-1945 hegemony which saw the USA, and the westen world, all benefit so much.
That's exactly the point. No amount of emotion today will persist the tests of time. You, as an ordinary inhabitant of the planet, like everyone else alive for the next 5 generations, will not exist on this planet anymore.
There is 0 chance that the opinion of "x country will never be trusted again" will occur as there is absolutely no control over the world you won't live in, nor have any significance of the elements involving discussions between countries happening today.
Those in charge at that time, who desire to achieve something, will.
Keep living the dream though, a few more years on this planet may hopefully help clarify the workings of this fact of life.
