Internet reports that the United States and Iran are scheduled to hold a new round of talks on the Iranian nuclear issue on the 15th. Before the talks, the United States decided to withdraw non-essential U.S. personnel and their families from the U.S. Embassy in Iraq and other places. At the same time, the U.S. Defense Secretary approved the voluntary evacuation of U.S. military families in the Middle East. U.S. President Trump said he was not optimistic about reaching an agreement. Iran sent dual signals. On the one hand, it believed that the two sides might even reach an agreement "soon", and on the other hand, it warned that if Iran was attacked after the negotiations broke down, it would take retaliatory actions and attack U.S. military bases in the Middle East.
