NBC reported Trump said Iran's nuclear-weapons program should be blamed on its
previous government. He recalled an Obama-era agreement negotiated by six
countries in which Iran limited nuclear activity in exchange for sanctions
relief and release of frozen assets; Trump withdrew the US from that deal during
his first term. He said any future agreement would not immediately unfreeze
Iranian assets or lift sanctions, adding "That's later. If they behave well, do
well, we'll start talking about those matters."
