A sharp escalation in attacks in the Strait of Hormuz and the Persian Gulf is threatening the shaky ceasefire between Iran and the United States as the two sides struggle to make progress in talks on a lasting end to the war. Iran accused the U.S. of ceasefire violations and issued new warnings Tuesday after two U.S. destroyers, closely followed by two merchant vessels, came under attack Monday morning during successful transits of the strait, in an expansion of U.S. operations in the waterway.Iran fired cruise missiles and drones at the U.S. naval and commercial vessels but did not land any hits, said Adm. Brad Cooper, head of U.S. Central Command. Iran also sent six fast boats after the commercial ships, he said, but U.S. forces fired on and destroyed the vessels. He would not say whether the exchange of strikes meant the ceasefire was over. Do you think that there are no winners in this war ?
