The comments made in Berlin yesterday by Tony Blinken on the continuing war tensions between the U.S. and Russia over Ukraine show a dangerous detachment from reality.  In stating before his meeting with Russian Foreign Minister Lavrov today, "I don't expect a breakthrough," he is demonstrating the delusional attitude of much of the Trans-Atlantic leadership, which is willing to risk a nuclear war, rather than take President Putin's demand for national security guarantees seriously.  Lavrov will likely call his bluff -- then how will Mr. Blinken respond?
