The reference was the same deployed by the wily 86-year-old theocrat to justify Iran's agreement to a landmark 2015 nuclear deal.
Speaking Thursday at a modest religious gathering in his office on Thursday, Supreme Leader Ali Khamenei recalled how the second Shia Imam, Hasan ibn Ali—seen by Shia Muslims as a paragon of just leadership—signed a controversial peace treaty with hated foe Mu'awiya in 661 CE.
The treaty, Khamenei said, was a calculated move to safeguard the long-term interests of Islam.
Although he made no direct mention of the ongoing nuclear negotiations with the United States, the allusion is almost certainly a subtle endorsement of diplomacy.
“Some people would come forth with complaints and objections when Imam Hasan made peace with Mu’awiya … it is temporary. The Imam has been recorded as saying that this incident, this domination of heresy and hypocrisy, is not meant to be permanent,” Khamenei said.
Khamenei’s tone marks a shift from early February, when he dismissed engagement with US President Donald Trump as “unwise, undignified, and dishonorable" after Washington reimposed so-called maximum pressure sanctions.
