The United States will resume military action and enforce an ironclad blockade against Iran if the nation fails to meet its commitments under the newly signed peace agreement, according to U.S. Secretary of Defense Pete Hegseth. Speaking in Brussels after a meeting with NATO ministers, Hegseth stated that the U.S. is prepared to act immediately if Iran deviates from the agreed-upon timeline for compliance.
What are the conditions for the U.S.-Iran agreement?
The memorandum of understanding, signed by President Donald Trump and Iranian President Masoud Pezeshkian, mandates the immediate and permanent cessation of military operations across all fronts, including Lebanon. According to the International Atomic Energy Agency (IAEA) director general Rafael Grossi, the agreement also requires the dilution of Iranian uranium stocks under agency supervision. While the document has been hailed as “historic” by President Pezeshkian, its enforcement remains tied to strict adherence to these technical and military benchmarks.

How does the Israel Defense Forces’ position affect the deal?
The current peace deal faces a significant hurdle regarding the status of southern Lebanon. While the agreement stipulates a total end to military operations, the Israel Defense Forces (IDF) have stated they will continue operating within a 10km “security zone” inside Lebanese territory. A senior Israeli official, speaking to Reuters, confirmed that Israel does not consider itself bound by the U.S.-Iran agreement, as it was not a party to the negotiations. This creates a direct policy collision between the U.S. diplomatic initiative and Israel’s stated military objectives.
Why has the U.S. criticized NATO allies?
Secretary Hegseth criticized several NATO allies for their reluctance to support U.S. military strikes against Iranian targets, characterizing their behavior as “shameful.” According to Hegseth, the U.S. requested access to European bases and ports to launch operations against threats in the Middle East, but was met with what he described as “arcane legal debates.” This tension highlights a growing divide between U.S. unilateral military strategy and the diplomatic caution favored by various European partners.
When international agreements are signed, watch for the “implementation gap.” As noted by UK Foreign Secretary Yvette Cooper, even when top-level deals are reached, the practical execution—such as the 20-point Gaza ceasefire plan—often stalls due to local administrative disputes and conflicting security priorities.
What are the future economic and diplomatic trends?
The global impact of the agreement is currently being measured through oil prices and diplomatic stability. President Trump has dismissed critics of the deal, citing record-high stock market performance and declining oil prices as indicators of success. Meanwhile, regional powers such as Pakistan and Turkey have expressed hope that the memorandum will foster lasting peace. However, diplomatic relations remain fragile; Israeli Foreign Minister Gideon Saar has announced the severing of all ties with EU foreign policy chief Kaja Kallas following reports that she compared Israel’s treatment of Palestinians to apartheid-era South Africa.
