During the panel in Bahrain, the dispute between the United States and Israel over how to deal with the Iranian nuclear issue came to the fore. 
Biden's adviser Brett McGrack: Trump's pressure did not work. Israel Security Adviser Hulata: It did!

At the IISS Menama Strategic Conference in Bahrain today (Sunday) a public disagreement arose between the positions of the United States and Israel, regarding the handling of the Iranian nuclear issue. At the conference, which deals with defense and foreign policy in the region, President Biden's senior adviser said that the Trump administration's pressure campaign against Iran had failed, and that the current administration "did not live in the illusion" that more pressure would change Iranian behavior. 

To this, Security Adviser Eyal Hulta replied that Iran "will not agree to the concessions only because we will ask them nicely."

Hulta explained his position, saying that "anyone who claims that pressure does not work should look at the previous rounds of pressure on Iran by two American governments. They helped make Iran change policy. We think Iran will not change policy unless we force it. Israel has said several times that it will defend. "On herself if we have to. We will make the preparations to do so."

Biden's adviser Brett McGrack said: "We are approaching the resumption of talks with Iran in Vienna. We hope that diplomacy will succeed - if it fails we will use other means. We will not allow Iran to acquire nuclear weapons. Military force will not change Iranian behavior but it can block its nuclear program ".
