KYIV, June 1 - Progress in political and diplomatic negotiations with Russia is impossible, as Russia has returned to its extremely aggressive initial rhetoric, which it uses in the domestic market, Mykhailo Podoliak, the adviser to the head of the President's Office, said in an exclusive interview with Interfax-Ukraine.

They have returned to the original aggressive rhetoric that they use in the domestic market, to talk about the war in the tone that they are allegedly right anyway: what is happening in Ukraine is staged, enemies are everywhere, NATO is everywhere. And they don't care how it looks from side ... This is an absurdity. They stopped perceiving the world as it is. There was a rollback," he said.
