On Tuesday, Barak is scheduled to join Prime Minister Benjamin Netanyahu's entourage at the United Nations headquarters in New York, ahead of the three-way meeting between Netanyahu, Obama and Palestinian President Mahmoud Abbas. The White House has already admitted it has "no grand expectations" from the summit.
The most urgent matter, the Iranian nuclear threat, was also discussed at the Pentagon, with Barak saying that he timeframe for harsh sanctions on Iran must be limited.
The two officials met at the Pentagon for a face-to-face meeting for about half an hour, and were later joined by a number of senior advisors and representatives.
Addressing the Iranian nuclear threat, on the backdrop of the Russian president's claim that Israel had promised not to strike in Iran, Barak said that the Jewish state "is not taking any option off the table. It means what is says, and it advises other countries to act the same way."
Before Gates, Barak met with American National Security Advisor James Jones and with Dennis Ross, who is in charge of the talks with Iran on behalf of the United States.
