Israel's government is alarmed that the United States is effectively legitimizing Iran's influence in Lebanon through new diplomatic understandings, according to two Israeli sources who spoke with Axios. Officials fear that a U.S.-Iran memorandum of understanding signed last week, alongside separate talks in Switzerland, will erode Israel's freedom to operate militarily on Lebanese soil.
The core concern is that Iran has successfully wrapped the Lebanon situation into its broader nuclear negotiations with the Trump administration. Israeli leaders believe the White House now feels it must contain Israeli strikes in Lebanon to advance its own diplomacy with Tehran. This marks a sharp reversal from months of close coordination between Washington and Jerusalem aimed at weakening Hezbollah.
U.S. officials, for their part, view the MOU as a necessary step toward a broader regional settlement. The document stipulates that both countries and their allies will end all hostilities, including in Lebanon, and commit to the country's territorial integrity — a condition undermined by Israel's ongoing military presence in the south.
The immediate worry in Jerusalem is a new pattern of U.S. pushback each time Israel plans a cross-border strike, or mounting American pressure to withdraw from southern Lebanon while Hezbollah still poses a threat. Israeli sources described the dynamic as a strategic trap: progress with Tehran comes at the direct expense of Israel's security buffer.
Counter-argument: Some analysts contend that the MOU is largely symbolic and that the Trump administration has repeatedly demonstrated strong backing for Israeli security. They argue the administration may view Lebanese sovereignty language as a diplomatic tool rather than a binding constraint on Israeli operations.
