Israeli anti-war protesters march with signs during a demonstration opposing military action against Iran in Tel Aviv on March 24, 2012.
The United States has rebuffed an Israeli demand to declare clear "red lines" that Iran must not cross.
US State Department spokeswoman Victoria Nuland said on Monday that the idea of deadlines or red lines is “not useful,” AFP reported.
Tension between Israel and the United States over Iran's nuclear energy program bubbled to the surface again on Monday when White House spokesman Jay Carney said that Washington insists there is still "time and space" to resolve the issue.
"We believe that there remains time and space for that effort to bear fruit…” he told reporters at a news briefing.
Earlier in the day, US Secretary of State Hillary Clinton said Washington is “not setting deadlines” for a diplomatic resolution of the dispute over Iran’s nuclear energy program.
At the beginning of 2012, the United States and the European Union imposed new sanctions on Iran’s oil and financial sectors with the goal of preventing other countries from purchasing Iranian oil and conducting transactions with the Central Bank of Iran.
The illegal US-engineered sanctions were imposed based on the unfounded accusation that Iran is pursuing non-civilian objectives in its nuclear energy program.
On September 2, Netanyahu called on the international community to set a "clear red line" for Iran to halt its nuclear energy program.
The US and Israel have repeatedly threatened to take military action against Iran in order to force the Islamic Republic to halt its uranium enrichment program, which Washington and Tel Aviv claim includes a military component.
Iran rejects the allegations, arguing that as a committed signatory to the nuclear Non-Proliferation Treaty (NPT) and a member of the International Atomic Energy Agency (IAEA), it has the right to use nuclear technology for peaceful purposes.
In addition, the IAEA has conducted numerous inspections of Iran's nuclear facilities but has never found any evidence showing that Iran's civilian nuclear program has been diverted to nuclear weapons production.
