Did Europe use its last card against Iran?

Pars Today - Foreign Policy magazine published an article discussing the activation of the snapback mechanism against Iran by France, Germany, and the UK.

The American magazine Foreign Policy recently expressed skepticism about the success of activating the snapback mechanism in an article, stating: "The reinstatement of UN Security Council sanctions is largely symbolic and cannot target Iran's economy like U.S. sanctions. Although Russia and China cannot prevent the return of these sanctions, they can disrupt their implementation." According to Pars Today, this situation arose because Iran did not agree to Europe's terms last week.

According to these terms, in exchange for a six-month suspension of the return of sanctions, Iran would have had to grant unlimited access to IAEA inspectors, disclose the location of its 400 kilograms of enriched uranium, and resume negotiations with the United States. 

However, the attacks by Israel and the United States on Iran have reduced the country's willingness to engage in these negotiations or grant access to IAEA inspectors. 

Nevertheless, the three European countries hope that by using their final pressure card and activating the snapback mechanism, they can change Iran's position—though this seems unlikely.

It is worth mentioning that Germany, France, and the United Kingdom activated the process of reinstating United Nations Security Council sanctions against Iran on Thursday, a mechanism known as "snapback." These three European countries, collectively referred to as the E3, were all parties to the 2015 Iran nuclear deal, which aimed to lift sanctions in exchange for restrictions on Iran's nuclear program. However, U.S. President Donald Trump withdrew from the agreement in 2018.
