An major international pact designed to stop the proliferation of nuclear arms has officially concluded, with Iran proclaiming the end of the 10-year-old arrangement.

Landmark Deal Formally Terminated

Iran announced on the weekend that it was free from obligations by the 2015-era agreement, formally known as the nuclear accord, under which global sanctions were removed in exchange for limitations on Tehran's atomic program.

From now on “all of the provisions [of the 2015 deal], encompassing the limitations on the Iranian atomic program and the related processes are regarded as concluded”, Iran’s ministry of foreign affairs announced in a statement.

Nonetheless, it noted that the nation “firmly expresses its commitment to diplomatic efforts”.

Context of the Deal

Concluded in the Austrian capital by Tehran, China, Britain, Paris, Germany, Russia and the US, the agreement aimed to end the long-standing diplomatic standoff and mark the start of a new era in relations between Iran and the west.

While the deal officially expires on Saturday, it has been in disarray for years.

Key Events Leading to the Termination

• In 2018, in his initial presidency, Donald Trump angered his European allies by independently taking the United States from the deal and reinstating restrictions.
• As a result of the US withdrawal, Iran started increasing its nuclear programme.
• EU-brokered negotiations to restore the agreement have not succeeded, and this summer’s military attacks on Iran by Israel and the US left hopes for a renewal at a record low point.

Latest Events

After the two-week war in last June, Iran’s parliament passed a law to decline to work with the UN nuclear watchdog, the United Nations' atomic inspectorate.

This resulted in signatories the UK, Germany and France triggering the so-called “snapback” mechanism, leading to the reinstatement of the United Nations restrictions.

Those snapback measures in effect made a formality of “the end date”, which was set for October 18, exactly 10 years after the adoption of UN security council resolution 2231.

International Responses

Recently, when the snapback restrictions were implemented, the UK, Paris and Berlin top diplomats announced in a combined declaration they would continue to pursue “a fresh political solution to ensure Iran does not gets a atomic weapon”.

The EU's chief diplomat, Kaja Kallas, remarked the sanctions “must not be the end of negotiations” and that “a sustainable resolution to the Iran's nuclear issue can solely be attained through talks”.

Prospective Outlook

Earlier this week, Trump stated that he desired a peace agreement with Iran, while Iran has repeatedly affirmed it is willing to diplomacy with the US, provided Washington offers guarantees against military action during any possible talks.

The 3 European nations also recently announced they would seek to restart negotiations to find a “all-encompassing, durable and confirmable agreement”.

However, ties between the Western countries and Tehran continue to be strained. The US had previously imposed large restrictions, encompassing trying to force all nations to avoid Iran's oil. Multiple rounds of mediated by Oman talks this year between Tehran and Washington failed to reach an agreement.

Iran’s top diplomat, Abbas Araghchi, stated recently that Tehran did “perceive no any justification to negotiate” with EU nations, given that they activated the automatic reinstatement mechanism.

Longstanding Accusations

European and American governments and Tel Aviv have for years accused Iran of attempting to acquire nuclear arms, a claim Tehran denies, claiming its program is energy and civil-focused.

Iran is expected to observe termination day with a statement later on on Saturday at the United Nations in NYC.
