TEHRAN —Ali Akbar Velayati, a senior adviser to the Leader of the Islamic Revolution, warned that Europe’s attempt to activate the “snapback mechanism” to reimpose UN sanctions on Iran will only deepen Europe’s global isolation.  Speaking to Al Mayadeen, Velayati said the move exposes the West’s long-standing hostility toward Iran and violates UN Security Council Resolution 2231. He described the mechanism as ineffective and merely a political propaganda tool aimed at pressuring Iran’s resistance front and hindering its scientific and defense progress.
