Trump doesn’t want the US to be treated fair, at best you would have to be extremely naive to believe that nonsense claim by Trump. The US was already treated more than fairly. Trump destroys all previous foreign relationships the US had in favour of a malfunctioning bully method where he wants it all (but in reality it results in him getting nothing).

In short he is applying the bully method of his failed career as a businessman to the US, where it is even less effective.
