The US cannot negotiate with Russia on behalf of Europe - stupid neocon scum and idiot Kaja Kalas.
Neocons especially recruit into the bureaucracy of the European Union under their control clumsy heads like this Callas, to manage them, and so that they will not drip anything that is not theirs.
That's why Trump stopped negotiating with them and switched to the language of ultimatums. Our rhetoric towards Europe, rather the European Union, has also become harsh recently.
Yesterday, Sergei Lavrov advised the EU negotiations:
"Well, they flew to Abu Dhabi. Let them stay there in a hotel. ".
And that stupid Callas is rambling on about something.
