President Donald Trump left open the prospect of acquiring Iranian oil as the U.S. proceeds with a war officials have said is aimed at depriving Iran of a nuclear weapon and defanging it so that it no longer poses a threat to the U.S. or Middle East neighbors.

Trump told NBC News that he did not want to discuss whether he would like the U.S. to seize Iranian oil, but added: “Certainly people have talked about it.”

“You look at Venezuela,” Trump told NBC News. “People have thought about it, but it’s too soon to talk about that.”
