Israel "shall prevail" if forced to fight Iran, "an evil, cruel and morally corrupt regime" bent on controlling the Middle East, Israeli President Shimon Peres said in Washington Sunday.

His speech to a powerful pro-Israel lobby charged up the atmosphere for talks Monday between U.S. President Barack Obama and Israeli Prime Minister Benjamin Netanyahu, who will tackle the perceived nuclear threat from Iran.

Hizbullah chief Sayyed Hassan Nasrallah stressed on Sunday that Jerusalem belongs to Palestine, Arabs, and the Muslims.

He said: “The choice to hold negotiations to return Jerusalem to Palestine are unrealistic because Israel considers the city as its permanent capital.”

Israel will take any decisions on Iran's nuclear activities as an "independent state," Foreign Minister Avigdor Lieberman said on Sunday, on the eve of a U.S.-Israel summit in Washington.

"Clearly, the United States is the biggest world power and the biggest and most important country that is a friend of Israel, but we are an independent state," Lieberman told Israeli public radio.

The Stuxnet computer virus sabotage of Iran's nuclear program was a "good idea" but it lent legitimacy to the use of malicious software as a weapon, according to a former CIA director.

"We have entered into a new phase of conflict in which we use a cyber weapon to create physical destruction," retired general Michael Hayden said in an interview with the CBS television show "60 Minutes" to be aired on Sunday.

Israel's Prime Minister Benjamin Netanyahu said Friday he will not set "red lines" for military action against Iran, insisting he wanted to preserve the Jewish state's freedom to maneuver.

"I have not set down red lines to the United States and will not set down red lines," he said. "I want to reserve Israel's freedom to maneuver in light of threats, every country would demand that."

President Michel Suleiman noted on Friday that Lebanon is witnessing a period of stability despite the unrest in the region, hoping that any action regarding oil exploration in the eastern Mediterranean would not take place against the country’s interests.

He said: “Any violation of our petroleum rights will lead to war.”

Israel is keeping the option of military action against Iran open if the international community does not halt its suspected nuclear weapons drive, Foreign Minister Avidgor Lieberman said Friday.

"We are still waiting. We want to believe that the international community will be able to handle this threat... But again we keep all options on the table," Lieberman said when asked about the possibility of a strike on Iran.

Israel's state comptroller has questioned Prime Minister Benjamin Netanyahu over lavish private trips abroad he made that were financed by businessmen, the Haaretz newspaper reported on Friday.

It said he was questioned in secret for more than two hours at the start of the week, over an affair which broke out almost a year ago after an investigation by a private television station, Channel 10.

The government commissioner to the military court charged on Friday two employees at the state-owned Ogero telecom company with collaborating with Israel.

Shawqi Z. and 42-year-old Walid Q. were arrested by the Lebanese army intelligence in southern Lebanon on suspicion of spying for Israel, As Safir daily said.

President Barack Obama on Thursday called U.S. support for Israel "sacrosanct," and said he wanted the country to maintain its "military superiority" as he prepares to meet with Prime Minister Benjamin Netanyahu.

The two leaders are expected to make discussions about Iran's nuclear development program a priority during their planned meeting Monday at the White House.
