Iran warned the U.S. that failure to honor commitments regarding Lebanon in a new peace memorandum could trigger reciprocal action.
The warning signals a potential flashpoint in the diplomatic framework intended to end regional conflict. If the terms regarding Lebanese sovereignty are ignored, the agreement could collapse before it is formally signed, risking a return to military escalation.
Iranian Foreign Ministry spokesperson Esmaeil Baqaei said the agreement requires respect for Lebanon's sovereignty and territorial integrity. He said the memorandum includes commitments aimed at ending military operations on all fronts, including Lebanon [1].
Tehran is specifically seeking the withdrawal of Israeli forces from Lebanon as part of the broader peace framework. Baqaei said Lebanon's sovereignty is repeatedly referenced in the document [1]. However, reports on the specific contents of the memorandum vary, with some sources stating the excerpt of the deal does not specify Lebanon [2].
This diplomatic tension follows a period of high friction, including a two-month U.S. naval blockade of Iranian ports that was lifted prior to the memorandum signing [3].
An unnamed Iranian official said the country has warned of reciprocal action if the commitments linked to Lebanon are not honored [4]. The move suggests that Iran views the stability of Lebanon as a non-negotiable component of its security arrangement with Washington.
The formal signing of the memorandum of understanding is currently scheduled for June 19, 2026 [5]. While some reports suggested a signing date of June 15 or 16, other sources indicate the process will conclude on the 19th [5].
“The agreement requires respect for Lebanon's sovereignty and territorial integrity”
The dispute over Lebanon highlights the complexity of the U.S.-Iran rapprochement, where regional proxy interests often complicate bilateral agreements. By linking the success of the peace memorandum to Israeli withdrawal from Lebanon, Iran is attempting to leverage its deal with Washington to achieve strategic goals against Israel, potentially turning a bilateral peace effort into a multilateral security crisis.
