Iran's Ambassador to the United Nations has said his country "cannot take all of the burdens anymore" of preserving the 2015 Iran nuclear agreement, officially known as the Joint Comprehensive Plan of Action (JCPOA).
Iran's President Rouhani has said the latest US sanctions against the country demonstrate Washington's "desperation" and will not succeed. President Trump signed further measures aimed specifically at Iran's supreme leader Ayatollah Khamenei on Monday.
Now, the question is, can the remaining parties to the JCPOA - in practice, the so-called E3 powers (Germany, France and the UK) - trigger the “snapback” mechanism is response to Iran's reaction? The answer - which Europe and hawks in Washington should bear in mind - is a simple “no”.
