Trump signs Iran deal, but nuclear and Israeli terms remain unresolved

Iran Peace Deal Analysis for June 18, 2026

Trump and Iran's president signed a 14-point agreement to end the war and reopen the Strait of Hormuz. Oil prices fell on the news. Pakistan confirmed the memorandum of understanding is in effect. Both leaders committed to a ceasefire and a framework for reopening global shipping lanes.

The agreement is far from complete. Iran demanded that Israel withdraw from Lebanon before any permanent peace. This demand sits outside the US-Iran talks and depends on Israeli decisions. The deal leaves the nuclear program and long-range missiles unresolved. Trump formally signed despite these gaps. Trump also told Reuters he could resume attacks if needed, undercutting the finality of what was just signed.

Shipping companies are hesitant to use the Strait. Maersk's CEO said allowing Iran to charge passage fees sets a dangerous precedent. Vessels are not yet sailing through the waterway despite Trump's urging. US intelligence found that Iran now has more control over the strait than before the war started, giving Tehran leverage it did not have before.

Republicans in Washington have reacted negatively. Trump spent energy defending the deal and attacking former President Obama rather than addressing the nuclear and missile gaps his own officials acknowledge. A ceasefire is not a peace deal. This one depends on Israeli military decisions, Iran's nuclear intentions, and whether global shipping will actually resume.
