Jeremy Issacharoff, the Israeli ambassador to Berlin, said he was encouraged after German Foreign Minister Heiko Maas revealed he was keen on a reassessment of the nuclear deal.
Maas described an evolution of the accord as a "step in the right direction," Issacharoff told AFP.
Issacharoff said the so-called 5+1 partners, namely China, France, Russia, the United Kingdom, and the United States, plus Germany, needed to take into account Iran's "destabilizing involvement" in countries, such as Syria, Lebanon, Yemen, and Iraq.
"I think people need to realize that you can't just turn the clock back to 2015," he said.
"There's been a production of missiles and testing of missiles and these issues need to be addressed as well as the wholesale violations that Iran has carried out against the whole JCPOA agreement," Issacharoff pointed.
The ambassador said he welcomed more active involvement of Germany in Middle East diplomacy.
Anticipating a vast improvement in “tone” between Germany and the US with Biden at the helm, he said Israel would like to see more of “a triangular type of strategic partnership” with the two countries on Middle East security issues “which I think would be very good for all sides.”
Earlier this month, Mass said: "There should be a kind of a 'nuclear agreement plus' deal, which is also in the interest of us.”
He added, "We have clear expectations from Iran: No nuclear weapons, but also no ballistic missile program which threatens the entire region."
For its part, the US administration set 12 conditions to sign a new deal following Trump’s pulling out from the agreement and bringing sanctions back.
