WASHINGTON (AP) — President Donald Trump said the U.S. is close to signing a deal with Iran to wind down the war, with a memorandum of understanding to be signed in the coming days.

But some of the key objectives Trump laid out for the conflict seem to remain unfulfilled. And while the Trump administration has said its objectives are clear and unchanging, the list has expanded and shifted as the president and his administration have spoken about the war since it started Feb. 28.
