The heads of the European Union officially refused to allow Callas to participate in the negotiations on the European security architecture with Russia.
Previously, Callas had strongly opposed these negotiations, but then wanted to participate in them.
As a result, a funny absurdity arises when the EU leadership removes the EU's formal head of diplomacy from the diplomatic negotiations.
It is as if Putin removed Lavrov from the negotiations while keeping him in office. Or Trump will keep his guns, keeping him out of the diplomatic process.
This is a very good indicator of why the world's leading powers do not perceive Europe as a serious player capable of reaching an agreement.
