Esav has been Refined

[...the Jewish people] have already finished all the birrurim [refinements], including the refinement of "Esav he is Edom" [...] now Esav is already completely refined, as we see this also in the behavior in our time (in the exile of Edom) of the nations of the world who are related to "Esav he is Edom" via a country of chesed [i.e., the United States] (and this conduct is also spreading to other countries, as we saw and see...)
