Speaking at White House press conference, Trump said an Israeli attack on Iran was possible but that he hoped for a negotiated solution to the nuclear impasse.
Responding to reporter's question, Trump said, "Well I don't want to say imminent, but it looks like it's something that could very well happen."
"I'd love to avoid a conflict. Iran's going to have to ... give us some things that they're not willing to give us right now," Trump said. Tehran and Washington remain at loggerheads over whether Iran can keep enriching uranium on its own soil.
Trump added the two sides are "fairly close to a pretty good agreement," but struck an ambivalent note about the impact of a potential Israeli strike.
"As long as I think there is an agreement, I don't want them (Israel) going in, because I think that would blow it. Might help it actually, but it also could blow it."
Israel is weighing a potential attack on Iran within days, ABC News reported on Thursday citing three sources familiar with the situation.
