Prime Minister Benjamin Netanyahu is set to speak before the U.N. General Assembly next week, and will dedicate the majority of his speech to the Iranian nuclear threat.
Despite the recent positive gestures between Tehran and Washington, the U.S. has stressed this weekend that in the case of Iran's nuclear program, words are not enough.
U.S. officials told their Israeli counterparts that they "remain skeptical" regarding Iran's intentions over its nuclear program, and that they plan to judge Iran according to its actions and not its Iranian President Hasan Rouhani's conciliatory messages, the New York Times reported.
"First of all, as relates to President Rouhani and the Iranian government, we've always made clear that we're going to make judgments based on the actions of the Iranian government, not simply their words," Deputy National Security Advisor Ben Rhodes told reporters on Friday.
Rhodes said Israel and the U.S. are "cooperating closely" on the issue, and that while Israel's concerns over the Iranian president's motives were justified, U.S. President Barack Obama's administration believes that a diplomatic solution can still be reached.
"I think given Israel's relationship with the United States and given our shared interests in preventing Iran from getting a nuclear weapon, we'll continue to closely cooperate on our assessment. Again, ours is that there remains time to pursue a diplomatic path," he said.
Rhodes attributed the change in the Iranian president's rhetoric to the broad sanctions promoted by the U.S. "What we've done is steadily, I think, exceed expectations in terms of the sanctions that we did put in place, that weren't just unilateral but that got other countries onboard to stop purchasing Iranian oil. And that's ultimately what had the impact on Iran."
When asked whether Obama will meet with Rouhani at the upcoming U.N. General Assembly, Rhodes said no such meeting was scheduled, but that U.S. has made clear it is "open to bilateral discussions with the Iranians at a range of levels."
French President Francois Hollande stated on Thursday that he intends to meet Rouhani at the U.N. assembly.
Meanwhile, President Shimon Peres concluded a series of meetings at the Yalta Conference. Peres described the ongoing developments in the Middle East, specifically in Syria, Egypt and Iran. Peres praised the developing dialogue between the Obama and Rouhani, but added that "the Iranians are sophisticated and very patient. More than declarations, they should be judged solely on actions."
