U.S. Vice President JD Vance sent a letter to Mohsen Rezaei, secretary of Iran's Supreme National Security Council, in an effort to restart peace talks between the two countries, according to American officials and sources familiar with the details who spoke to The Wall Street Journal. One source said the letter was sent at the direction of U.S. President Donald Trump and that the president is aware of the move. Vance is examining whether Iran and the United States can find enough common ground to convince Trump not to give the final order for a short, intense attack on Tehran in the coming weeks.
