An important international agreement designed to curb the proliferation of nuclear arms has formally terminated, with Iran proclaiming the conclusion of the 10-year-old arrangement.

Landmark Deal Formally Terminated

Iran declared on the weekend that it was free from obligations by the 2015-era agreement, officially referred to as the nuclear accord, under which international restrictions were lifted in exchange for limitations on Iran's atomic program.

Moving forward “all of the provisions [of the 2015-era deal], encompassing the restrictions on the Iranian atomic program and the associated processes are considered concluded”, the Iranian ministry of foreign affairs stated in a official communication.

Nevertheless, it clarified that the country “strongly declares its dedication to diplomatic efforts”.

Context of the Deal

Concluded in the Austrian capital by Iran, Beijing, the UK, Paris, Berlin, Moscow and the United States, the pact aimed to end the years-long political dispute and mark the start of a new era in ties between Iran and the Western nations.

Although the agreement formally expires on Saturday, it has been in disarray for years.

Key Events Leading to the End

• Back in 2018, in his initial presidency, Donald Trump angered his European partners by unilaterally withdrawing the US from the deal and reimposing sanctions.
• As a result of the American exit, Tehran started stepping up its nuclear programme.
• EU-brokered talks to restore the agreement have failed, and recent airstrikes on Tehran by Israel and the United States left hopes for a revival at a record low point.

Recent Developments

After the two-week war in June, Iran’s parliament approved a bill to decline to cooperate with the IAEA, the UN’s atomic monitoring body.

This resulted in participants the UK, Germany and Paris activating the known as “snapback” mechanism, leading to the re-imposition of the United Nations restrictions.

Those automatic sanctions in effect made a formality of “the end date”, which was scheduled for October 18, exactly 10 years after the adoption of Resolution 2231.

Global Responses

Last month, when the automatic restrictions went into effect, the British, Paris and Berlin foreign ministers said in a joint statement they would continue to pursue “a fresh diplomatic resolution to ensure Tehran never gets a nuclear weapon”.

The EU's top diplomat, the EU foreign policy chief, said the measures “cannot be the conclusion of negotiations” and that “a sustainable resolution to the Iranian atomic problem can solely be attained through talks”.

Prospective Outlook

On Monday, former President Trump said that he wanted a peace deal with Tehran, while Tehran has consistently said it remains open to negotiations with the US, on condition that Washington offers assurances against military action during any potential discussions.

The three European nations also last week declared they would seek to resume negotiations to reach a “comprehensive, durable and verifiable agreement”.

Still, relations between the Western countries and Tehran continue to be strained. The US had previously enforced extensive restrictions, including trying to compel all countries to shun Iranian crude oil. Multiple sessions of mediated by Oman talks in recent months between Tehran and Washington failed to reach an agreement.

Iran’s foreign minister, Abbas Araghchi, said last week that Iran did “perceive no any justification to engage in talks” with EU powers, given that they triggered the snapback process.

Persistent Accusations

Western authorities and Tel Aviv have long alleged Tehran of seeking to obtain nuclear weapons, a allegation Iran rejects, stating its program is energy and civil-focused.

Iran is anticipated to mark the official end date with a statement subsequently on the weekend at the UN in NYC.
