WASHINGTON (AP) — Secretary of State John Kerry on Sunday tried to calm tensions with Israel before Prime Minister Benjamin Netanyahu's congressional address, yet insisted the Obama administration's diplomatic record with Iran entitles the U.S. to "the benefit of the doubt" as negotiators work toward a long-term nuclear deal. On a mission to warn of the dangers of a nuclear-armed Iran, the prime minister arrived in Washington for the speech the White House didn't want him to give.
Kerry said in an interview broadcast before he arrived in Switzerland for talks with Iran's foreign minister that Netanyahu was welcome to speak in the U.S. and that the administration did not want the event "turned into some great political football."
That sentiment was a step back from some of the sharp rhetoric between the allies in recent weeks, and Kerry mentioned that he talked to Netanyahu as recently as Saturday.
But Kerry stressed that Israel was safer as a result of the short-term nuclear pact that world powers and Iran reached in late 2013, and he described that improvement as the "standard we will apply to any agreement" with the Islamic Republic.
Officials have described the United States, Europe, Russia and China as considering a compromise that would see Iran's nuclear activities severely curtailed for at least a decade, with the restrictions and U.S. and Western economic penalties eased in the final years of a deal.
"We are going to test whether or not diplomacy can prevent this weapon from being created, so you don't have to turn to additional measures including the possibility of a military confrontation," Kerry told ABC's "This Week."
"Our hope is that diplomacy can work. And I believe, given our success of the interim agreement, we deserve the benefit of the doubt to find out whether or not we can get a similarly good agreement with respect to the future."
Netanyahu will press his opposition to a diplomatic accommodation of Iran's program in his speech Tuesday to Congress. "We are not here to offend President Obama whom we respect very much," said a Netanyahu adviser, who was not authorized to be identified. "The prime minister is here to warn, in front of any stage possible, the dangers" of the agreement that may be taking shape.
The adviser, who spoke shortly before the delegation touched down in Washington, said Israel was well aware of the details of the emerging nuclear deal and they included Western compromises that were dangerous for Israel. Still, he tried to lower tensions by saying that Israel "does not oppose every deal" and was merely doing its best to warn the U.S. of the risks entailed in the current one.
The invitation to speak to Congress extended by House Speaker John Boehner, R-Ohio, and Netanyahu's acceptance have caused an uproar that has exposed tensions between Israel and the U.S., its most important ally.
By consenting to speak, Netanyahu angered the White House, which was not consulted in advance, and Democrats, who were forced to choose between showing support for Israel and backing the president.
"I will do everything in my ability to secure our future," Netanyahu said before flying to Washington.
Boehner said Iran's nuclear ambitions were a threat well beyond the region.
"We're not going to resolve this issue by sticking our heads in the sand," Boehner told CBS' "Face the Nation."
He said Netanyahu "can talk about this threat, I believe, better than anyone. And the United States Congress wants to hear from him, and so do the American people."
The congressional speech also has sparked criticism in Israel, where Netanyahu is seeking re-election on March 17. He also planned to speak Monday at the annual conference of the pro-Israel lobby AIPAC.
Netanyahu considers unacceptable any deal that does not entirely end Iran's nuclear program. But President Barack Obama is willing to leave some nuclear activity intact, backed by safeguards that Iran is not trying to develop a weapon. Iran insists its program is solely for peaceful energy and medical research.
The dispute has become more personal of late.
Last week, Obama's national security adviser, Susan Rice, described the timing and partisan manner of Netanyahu's visit as "destructive" for the U.S.-Israeli relationship.
On Sunday, Kerry painted a more positive picture of continued close cooperation. He said the U.S.-Israeli security partnership was closer than at any point before, and noted the large investment of American money in the Jewish state's Iron Dome missile defense system.
He said the U.S. government has "intervened on Israel's behalf in the last two years a couple of hundred" times in more than 75 forums "in order to protect Israel."
Kerry plans to make precisely that point when he addresses the U.N. Human Rights Council on Monday in Geneva.
U.S. officials have often accused the council of being biased against Israel and inappropriately focused on the Jewish state. Officials traveling with Kerry said he would urge the council to take a more balanced approach.
