Trump says Israeli attack on Iran 'could very well happen'

US President Donald Trump suggested at a White House press conference on Thursday that an Israeli attack on Iran was possible.

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."

"Look, it's very simple, it's not complicated. Iran cannot have a nuclear weapon. Other than that, I want them to be successful. I want them to be tremendous. We'll help them be successful. We'll trade with them. We'll do whatever is necessary."

Trump said he aimed to avoid a conflict and sought peace.

"I'd love to avoid a conflict. Iran's going to have to negotiate a little bit tougher, meaning they're gonna have to give us some things that they're not willing to give us right now," Trump said.

"I've kept us out of wars ... I believe in peace through strength. We have the greatest military in the world."
