EU and Iran on the Brink of a New Crisis: Nuclear Talks in Istanbul and the Threat of Sanctions Return

Iran
has officially confirmed that on July 25 in Istanbul, a new round of nuclear consultations
will be held with representatives of Germany, France, and the United Kingdom. The main topic
of the talks will be the implementation of obligations under the Joint Comprehensive Plan of
Action (JCPOA) and the prevention of further escalation around
Iran’s nuclear program.
The European side has set a strict deadline: if significant
progress is not achieved by the end of August, the so-called “snapback”
mechanism – the automatic reinstatement of UN Security Council sanctions – will be triggered. This
could lead to full
diplomatic and economic isolation of Tehran, reminiscent of the
2012–2015 situation.
According to European diplomats, this step is “not a threat
but a measure to protect international security.” However, experts warn that
such an ultimatum might push Iran toward radical actions.
Iran, represented by its Foreign Ministry and the Supreme National Security Council,
declared its readiness to cooperate with the International Atomic Energy Agency (IAEA)
but emphasized that any inspections require separate approval from the Council.
Tehran insists that allowing foreign inspectors “could pose a national security
risk,” especially after the series of Israeli and US attacks on Iranian nuclear facilities in June.
Experts from the Institute for the Study of War (ISW) note that the “snapback” ultimatum is more of a pressure tool
than an immediate plan to reimpose sanctions. The EU fears that a new wave of
isolation could lead to the radicalization of Tehran and a possible closure of the Strait of Hormuz,
through which 25% of global
oil and LNG exports pass.
According to Middle Eastern analysts from Omni and RadioFreeEurope,
Iran is trying to buy time until
autumn to strengthen its negotiating position, complete the
modernization of its nuclear facilities, and bolster its military presence in
the Persian Gulf.
The issue of whether to grant or deny access to IAEA
inspectors may become the main bargaining chip. Tehran is likely to use it as leverage
to ease sanctions, but in the event of failed negotiations, it may further restrict access to key
nuclear sites.
If
even minimal progress is achieved in Istanbul (for example, partial IAEA
access), Europe may delay the activation of the “snapback” mechanism. However, if the talks reach a deadlock, the world could face a new wave of energy and political
crises as early as September.
