Thank you for your editorial "Nobel Peace Prize: How the U.S. can maintain its moral authority in a world opposed to nuclear weapons" (Oct. 3). Hopefully, it woke up many readers to the serious peril the world is facing due to President Donald Trump's currently unlimited authority to launch a first nuclear strike. Hopefully, Congress will quickly recognize how important are the anti-first strike bills just submitted to Congress by Sen. Ed Markey (D-Mass.) and Rep. Ted Lieu (D-Calif.).Herman M.
