This piece was written by six former ambassadors to Iran from European countries: Richard Dalton (United Kingdom), Steen Hohwü-Christensen (Sweden), Paul von Maltzahn (Germany), Guillaume Metten (Belgium), François Nicoullaud (France) and Roberto Toscano (Italy)
As ambassadors to Iran during the last decade, we have all followed closely the development of the nuclear crisis between Iran and the international community. It is unacceptable that the talks have been deadlocked for such a long time.
The Arab world and the Middle East are entering a new epoch in which no country is immune from change. This includes the Islamic Republic of Iran, which is facing the disaffection of a significant part of its population. Such a period of uncertainty offers opportunities for reconsidering the West’s established position on the Iranian nuclear question.
In terms of international law, the position of Europe and the United States is perhaps less assured than is generally believed. Basically, it is embodied in a set of resolutions adopted by the U.N. Security Council authorizing coercive measures in case of "threats to the peace."
But what constitutes the threat? Is it the enrichment of uranium in Iranian centrifuges? This is certainly a sensitive activity, by a sensitive country, in a highly sensitive region. The concerns expressed by the international community are legitimate, and Iran has a moral duty, as well as a political need, to answer them.
