US President Donald Trump said he doesn't know what the future holds for Iran.

“They [i.e. Iran] were going to hang 837 people, and… we let them know that if that happens, that will be a very bad day for them, and they decided not to do it,” Trump said at the White House press conference Tuesday. “I can’t tell you what’s going to happen in the future, but supposedly they’ve taken that off the table.”
