The US national security adviser held talks Wednesday with Israeli Prime Minister Naftali Bennett, who expressed his concern that negotiations in Vienna on Iran's nuclear program had "profound ramifications" for Israeli security.

Jake Sullivan, the national security adviser to President Joe Biden, said his visit to occupied Palestine came during "a critical juncture."

"It's important that we sit together and develop a common strategy, a common outlook, and find a way forward that fundamentally secures your country’s interests and mine," Sullivan said, according to an Israeli government statement. 

He did not directly refer to Iran but the Israeli statement revealed that the meeting focused on the Vienna talks. 

Bennett called for the suspension of negotiations, accusing Iran of "nuclear blackmail", which could harm "Israel". 

It is worth noting that it has been weeks, and the White House is yet to respond to Israeli Prime Minister Naftali Bennett's request for a phone call with US President Joe Biden.

Reviving the JCPOA

Moreover, the Biden administration has warned it may soon be too late to revive the JCPOA. 

"It really depends on the pace of their nuclear process," said Malley, the US special envoy for Iran. "If they halt the nuclear advances, we have more time."

"If they continue at their current pace, we have some weeks left but not much more than that, at which point the conclusion will be there's no deal to be revived," he said.

However, Iran says it only wants to develop a civil nuclear program.
