While watching The News Hour on PBS, I heard a news person describe John Kerry and the Iranian representative being "at loggerheads". Not sure of the phrase's actual meaning, I looked it up.
in stubborn dispute or disagreement. "council was at loggerheads with the government over the grant allocation"
synonyms: in disagreement, at odds, at variance, wrangling, quarreling, disagreeing, disputing, locking horns, at daggers drawn, in conflict, fighting, at war; at each other's throats. "the European Union and the United States are at loggerheads over how to reduce greenhouse gases."
The news person probably meant, "No positive results were obtained."
And that's not news.
