NEW YORK — President Donald Trump said Wednesday that achieving peace between the Israelis and Palestinians may be the “toughest deal of all” that he’s tried to negotiate, adding that his administration nonetheless is working hard for peace in the region. He said there’s a “pretty good shot” he can broker an agreement that has eluded several of his predecessors. “We are looking seriously at peace and maybe ultimately peace for the whole of the Middle East and I think we have a pretty good shot, maybe the best shot ever,” the president said as he opened a meeting with Palestinian Authority President Mahmoud Abbas. “It’s a complex subject, always been considered the toughest deal of all: peace between Israel and the Palestinians, the toughest of all,” Trump continued.
