"We should not pretend that the situation will automatically improve with a regime change in Tehran by outside forces. This approach has already failed, for example, in Iraq", he said.

He also noted that if one wanted to improve the situation for the Iranians, there was no point in ending the dialogue.

"Then, we should talk to Iran and demand compliance with human rights. In any case, solely threats and military escalation have brought nothing. We want to prevent a flare-up in the Middle East", he urged.

Maas called on Germany’s allies to take the European approach to the crisis, namely the EU’s reliance on diplomacy instead of escalation, and defended the 2015 Iran nuclear deal.

"Without the agreement, Iran would probably already have an atomic bomb. We absolutely must prevent it from getting this far", he warned.

At the same time, Maas urged Tehran to abide immediately by the obligations under the Joint Comprehensive Plan of Action, although it scrapped its remaining limitations under it in the wake of the deadly attack on Iranian top commander Qasem Soleimani.

"The increased uranium enrichment must come to an end. The International Atomic Energy Agency must continue to have access to all facilities in Iran to check this closely," Maas concluded.
