A senior U.S. official said there is an 85% [1] chance that a memorandum of understanding to end combat between the U.S. and Iran will be signed within days.

The agreement represents a critical effort to cease active hostilities and secure guarantees that Iran will not develop or acquire nuclear weapons.

Iranian Foreign Minister Araqchi said the document consists of two stages and spans less than two pages [2]. Despite the brevity of the text, the negotiations have reached a final stage. The U.S. government said the agreement includes a promise from Iran to forgo nuclear weapons development [1].

However, contradictions remain regarding the scope of the deal. While U.S. officials emphasize the nuclear guarantees, other reports indicate that nuclear development issues are not included in the document, a point highlighted by the Iranian side [1].

This push for a signature follows a period of strategic patience from the White House. President Donald Trump previously instructed his delegation not to rush the agreement, saying that time was on the side of the U.S. [1].

Recent reports note that Trump has spoken on the matter 39 times [1]. The current optimism from senior officials suggests a shift toward finalizing the terms, though the official said the probability of success is "about 85% and not 100%" [1].

"about 85% and not 100%"

The discrepancy between the U.S. and Iranian accounts of the memorandum's content—specifically regarding nuclear weapons—suggests that while a ceasefire may be imminent, the core strategic tension over Iran's nuclear program remains unresolved. The short length of the document indicates a framework for a truce rather than a comprehensive peace treaty.
