On August 8, 2025, Armenia and Azerbaijan signed a US-brokered peace agreement at the White House, formally ending decades of conflict and recognizing Soviet-era borders. The deal, facilitated by former President Donald Trump, includes economic cooperation and a US-backed transit corridor known as the Zangezur Corridor, linking Azerbaijan to its Nakhchivan exclave through Armenian territory. While the agreement has been welcomed as a historic step toward regional peace, it has faced opposition and skepticism from various quarters. Iran, through senior adviser Ali Akbar Velayati and other officials, has strongly opposed the establishment of the US-backed corridor, warning it threatens regional security, could divide Armenia, and alter the geopolitical balance. Tehran has pledged to block the corridor's creation, with or without Russian cooperation, describing it as a potential NATO wedge near its northern border and a threat to its trade routes. Iran also opposes the disarmament of Hezbollah in Lebanon, reaffirming its support for the group and criticizing Lebanese government plans to disarm the militia. In response, Lebanon's President Joseph Aoun has rejected any foreign interference in the country's internal affairs, including Iran's statements on Hezbollah, emphasizing Lebanon's sovereignty and the government's intent to proceed with disarmament. Iranian Supreme National Security Council Chairman Ali Larijani has reiterated Iran's non-intervention stance in Lebanon's internal matters while expressing continued support for resistance movements. The peace deal marks a significant diplomatic achievement for the United States but faces challenges from regional actors wary of shifts in influence and security dynamics.
