In this file photo taken on Monday, July 16, 2018, U.S. President Donald Trump shakes hand with Russian President Vladimir Putin at the end of the press conference after their meeting at the Presidential Palace in Helsinki, Finland. Pavel Palazhchenko was a constant presence as chief interpreter for Soviet leader Mikhail Gorbachev and Foreign Minister Eduard Shevardnadze, and watched from Moscow to see how the latest chapter in the US-Soviet story would unfold. During an interview Monday July 23, 2018, Palazchenko declined to call the latest Helsinki meeting between US President Trump and Russian President Putin an outright failure, but said there seems a lack of clarity on exactly what the two agreed on.
