Prime Minister Benjamin Netanyahu was speaking on Thursday with CNN's Fareed Zakaria in Davos, Switzerland, on Middle Eastern topics including the Iran nuclear deal at the World Economic Forum.
Netanyahu earlier met with US Secretary of State John Kerry on the sidelines of the meeting.
Netanyahu's office reported that part of the meeting was held privately between the two leaders and that it was a "very good" good meeting.
Kerry and Netanyahu discussed Syria, Iran, Islamic State, and the Palestinian issue.
Before the meeting with Kerry, Netanyahu met with US Vice President Joe Biden in what was described by the Prime Minister's Office as a "warm and friendly" meeting. The two leaders discussed security, energy, and Middle East strategy issues.
