An adviser to Iran’s supreme leader said the country has entered a new phase of deterrence, warning that Tehran will globalise the consequences of US “mistakes”.

“[The] Islamic Republic of Iran is in a new phase of deterrence; the notion of delivering a low-cost strike against Iran is a miscalculation that could have consequences extending far beyond the military arena to the energy markets and the global economy,” Ali Akbar Velayati said in an X post, The Caspian Post reports, citing Al Jazeera.

“The White House should know that by threatening Iran and mobilising regional allies and activating the European lobby, it will not achieve greater security and stability; rather, it will globalise the consequences of its mistakes,” he added.

Iran’s senior leadership has repeatedly threatened to widen the war if the US intensifies its attacks. Power and water desalination plants in Kuwait have been repeatedly attacked in recent days, which GCC neighbours have condemned.
