GENEVA – In a landmark diplomatic breakthrough, the United States and Iran have reportedly reached an unprecedented agreement to formally acknowledge and perpetuate their core disagreements, effectively codifying a state of perpetual mutual annoyance that has defined their relationship for decades.

The new 'Treaty of Principled Antagonism' outlines key areas where both nations pledge to remain steadfastly at odds, including Iran's nuclear ambitions, its ballistic missile program, and its support for regional militant groups. The US, in turn, has committed to maintaining its 'deeply held concerns' and 'unwavering disapproval' regarding these issues, promising to issue strongly worded statements at regular intervals.

"This is a monumental step forward in ensuring absolutely nothing changes," declared Dr. Eleanor Vance, Head of Existential Futility Studies at the Global Institute for Stagnation. "By formalizing their disagreements, both sides can now focus on perfecting their respective grievances without the pesky distraction of accidental resolution."

Sources close to the negotiations, who spoke on condition of anonymity because their job relies on things never being resolved, indicated that the agreement includes a clause for quarterly 'Concern Enhancement Workshops' and an annual 'Ballistic Missile Program Justification Symposium' to ensure both parties remain fully invested in the status quo.

"We've moved beyond the naive hope of understanding," explained Ambassador Reginald Piffle, Undersecretary for Perpetual Diplomatic Gridlock. "Now, we can simply agree to disagree, loudly and publicly, forever. It's a win-win for everyone involved in the international relations industrial complex."
