Israeli Prime Minister Benjamin Netanyahu said on Tuesday that international sanctions were hurting Iran's economy but not enough to persuade it to curb its nuclear ambitions even slightly.

"The Iranian government ... is having economic troubles but it has yet to move backward, even a millimeter, in its nuclear program," Netanyahu told a news conference he called to mark his right-wing government's third anniversary in power.

"Will these difficulties bring the government in Tehran to stop its nuclear programe? Time will tell. I cannot say to you that this will happen. I know there are difficulties, but there has yet to be a change."

In the press conference, Netanyahu also talked about his governments domestic achievements, saying that In its first three years, the government "has brought about a series of reforms and important structural changes that helped the economy grow, helped reduce social disparities and helped Israel through the severe economic crisis of 2008 and 2009.

Guests at the press conference received a thick booklet marking the steps the government has taken, which include lowering the unemployment rate and improving Israel's credit rating, as well as lowering gasoline and electricity prices.

Netanyahu's comments on Iran came after a senior Revolutionary Guards commander was quoted as saying that the United States would not be safe from retaliation if Washington attacked Iran in an attempt to blunt its nuclear program.

On Friday, U.S. President Barack Obama vowed to press ahead with tough sanctions on Tehran, saying there was sufficient oil supply in the world market to allow countries to cut Iranian imports.

In his own remarks, Netanyahu shed no new light on how Israel might deal with what he has said is Iran's intention to build atomic weapons that could threaten the existence of the Jewish state.

Both Israel, widely believed to be the Middle East's only nuclear power, and its main ally, the United States, have held out the prospect of military action against Iran if sanctions do not work. Iran has said it is enriching uranium for peaceful purposes.

Returning to a familiar theme in Israel's discourse on Iran, Netanyahu contrasted the helplessness of Jews during the Nazi Holocaust to the military strength and diplomatic influence of the Jewish state founded after World War Two.

"The Jewish people did not have these capabilities seventy, eighty years ago. We did not have these tools. Today these tools exist, and it is our duty to use them in order to thwart the nefarious intentions of our enemies," he said, without referring directly to Iran.

A rash of public comments two months ago by Israeli officials suggesting time was running out for Israel to mount any effective military strike against Iranian nuclear facilities, some of which have been moved underground, stoked international concern.

But more recently, Israel has cautiously welcomed the planned resumption later this month of big-power nuclear talks with Iran.

"I will do all I can to fend off this danger," Netanyahu said in reference to Iran's nuclear program, "I hope we will be able to do this together with the leading players in the international community, it is a great danger to them, but first and foremost it is a danger to us."
