Iran's foreign minister said in June 2026 that a tentative deal to end its war with the United States would require Israel to withdraw forces from Lebanon.

Israeli forces entered southern Lebanon in 2024 during operations against Hezbollah, and a November 2024 ceasefire required phased withdrawals that have remained partially incomplete.

Under U.S. law, the executive branch can negotiate international agreements, but any binding commitment involving a treaty ally typically requires that ally's separate consent.
