The evidence provided details multiple aspects of US-Iran talks in Islamabad (e.g., Wikipedia mentions talks on 11 and 12 April 2026, and web searches discuss the agenda), but none of the retrieved sources directly confirm the specific sequence of events described: Trump sending officials to Islamabad *just 24 hours after* Iran closing the Strait of Hormuz, nor does any source analyze this specific sequence to conclude it signals the waterway is a bargaining asset. The claim is highly specific and lacks corroboration across independent sources.

The evidence mentions Iran's demands in the context of negotiations (e.g., 'Iran's 10-point proposal for peace calls for Iranian oversight of the Strait of Hormuz'), but none of the retrieved sources explicitly list the three specific demands mentioned in the claim: 'a ceasefire in Lebanon, an end to the US blockade on Iranian ports and progress on Iranian asset releases.' This specific combination of three demands is not corroborated.

The evidence mentions Iran's reaction to the ceasefire and the role of Abbas Araghchi, noting that Araghchi announced something on Friday morning. However, the claim's detailed narrative—that Iran viewed the two-week ceasefire in Lebanon imposed by Trump as significant, expecting a reciprocal partial lifting of the chokehold, *as announced by Araghchi in a tweet on Friday morning*—is too specific and lacks corroboration from multiple independent sources.

The evidence confirms the context of expectations regarding the blockade and the ceasefire (e.g., 'The US naval blockade of maritime traffic entering and leaving Iranian ports has been continuing this weekend'), but it does not contain multiple independent reports confirming the specific expectation that *in return for the ceasefire, Trump would lift the US blockade of Iranian ports* as a clear, established expectation.
