President Donald Trump and Iran's top negotiator reached a tentative deal Monday to end the U.S.–Iran war and reopen the Strait of Hormuz [1, 3].

The agreement aims to stabilize global shipping and prevent nuclear proliferation in a region that has seen escalating hostilities. Because the Strait of Hormuz is a vital artery for global energy markets, its reopening is critical for international economic stability [1, 4].

The deal includes guarantees that Iran will not develop nuclear weapons [2]. President Trump said, "We have secured iron‑clad guarantees that Iran will not pursue a nuclear weapon" [2].

While the agreement was signed remotely, both parties have planned a formal signing ceremony in Geneva, Switzerland [3, 5]. Some senior officials describe the memorandum of understanding as already signed, though other reports characterize the deal as tentative pending the formal ceremony [1, 3].

John Kirby, White House National Security Council spokesperson, said, "This agreement will bring an end to the conflict and reopen the vital Strait of Hormuz" [1]. The reopening follows a closure of 30 days [1].

Earlier negotiations in May included a tougher peace proposal from the U.S. and a proposed cease-fire duration of 60 days [4, 6]. The conflict had reached day 92 by the time of recent coverage [7].

Ned Price, U.S. State Department spokesperson, said, "The United States remains committed to a durable peace in the region" [5].

"This agreement will bring an end to the conflict and reopen the vital Strait of Hormuz."

The resolution of the U.S.–Iran conflict on day 92 represents a significant shift in Middle East geopolitics. By securing nuclear non-proliferation guarantees and restoring access to the Strait of Hormuz, the deal addresses the two primary security and economic concerns of the international community. The transition from a remote signing to a formal ceremony in Geneva suggests a phased approach to diplomatic normalization.
