JERUSALEM, Israel -- Israeli Prime Minister Benjamin Netanyahu says the international community doesn't have the resolve to deal with Iran's nuclear program. The time has come, he says, to draw that red line.
Netanyahu says he's going to the United Nations to urge world leaders to get tough with Iran.
Against the appeals of Israel and the United States, U.N. Secretary-General Ban Ki-moon joined 120 countries in Tehran last week for a summit of non-aligned nations. Iran says it's proof it's not isolated.
And government spokesman Mark Regev says they could be right.
"Last week, I didn't see a lot of diplomatic pressure on Iran. On the contrary we saw 120 states pay their respects to Iran," Regev told CBN News.
Israel has been sounding the alarm about Iran's nuclear ambitions for years. Despite economic sanctions imposed by the international community, Netanyahu says it's not enough. He says clear red lines need to be spelled out to Tehran.
"They have to stop their nuclear program," Regev said. "They have to stop all enrichment, and material that has already been enriched has to be moved out of Iran to a third country," he said. "(And) they have to dismantle that underground nuclear facility near Qom."
At the summit, Supreme Leader Ayatollah Ali Khamenei insisted Iran's nuclear program is for energy only.
But in a recent report, the International Atomic Energy Agency said Iran has doubled the number of centrifuges to enrich uranium at its underground facility in Qom.
Meanwhile, the open disagreement between Israel and the United States over the timing of a military strike continues.
U.S. Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, puzzled Israelis when he said he wouldn't want to be "complicit" in an Israeli strike against Iran.
Earlier this summer, U.S. Defense Secretary Leon Panetta said the United States would not allow Iran to obtain a nuclear weapon.
"We have options that we are prepared to implement to ensure that does not happen," Panetta said.
But Israeli Defense Minister Ehud Barak said then that time is running out.
"We really have something to lose by this stretched time upon which sanctions and diplomacy takes place because the Iranians are moving forward not just in enrichment," Barak said.
