WASHINGTON (AP) -- In the face of Israeli outrage over the Iran nuclear accord, the Pentagon is moving quickly to reinforce arguably the strongest part of the U.S.-Israeli relationship: military cooperation.
But officials say Washington has no plans to offer new weaponry as compensation for the Iran deal.
Defense Secretary Ash Carter left for Tel Aviv on Sunday to push ahead with talks on ways the U.S. can further improve Israel's security — not just with Iranian threats in mind, but an array of other challenges, including cyberdefense and maritime security.
Israel also has expressed concern that U.S. sales of advanced weaponry to Gulf Arab states has the potential of offsetting, to some degree, Israel's qualitative military edge.
Aides said in advance of the trip that although Carter strongly supports the Iran deal, he had no intention of trying to reverse Israeli opposition to it. Israeli Prime Minister Benjamin Netanyahu has denounced the deal as a mistake of historic proportion.
Carter is scheduled to meet with Netanyahu and Israeli Defense Minister Moshe Yaalon, as well as with Israeli generals, and visit troops in northern Israel. He plans to stop in Jordan and Saudi Arabia, U.S. allies whose leaders also are worried about implications of the nuclear deal.
On the day the Iran accord was announced, Carter issued a statement saying the U.S. is "prepared and postured" to help Israel improve its security, although he offered no specifics. He added that the U.S. would "use the military option if necessary" to protect its allies, to "check Iranian malign influence" and to ensure freedom of navigation in the Gulf.
The U.S.-Israel defense relationship has deepened in recent years, even as tensions between the two over how to contain Iran's nuclear program has grown.
The U.S. has invested hundreds of millions in an Israeli air defense system known as Iron Dome, designed to shoot down short-range rockets, mortars and artillery shells fired into northern Israel from southern Lebanon and into Israel's south from the Gaza Strip. The U.S. has worked with Israel on anti-missile systems and a wide range of other defenses. Two years ago the Pentagon committed to providing advanced radars for Israel's fleet of fighter jets and KC-135 refueling aircraft, and making Israel the first country to buy the V-22 Osprey hybrid airplane-helicopter.
Just two months ago Washington announced a $1.9 billion arms sale to Israel for a range of missiles and bombs, including bunker busters that can penetrate reinforced defenses to reach underground targets. Not included is the Pentagon's biggest bunker buster bomb.
Israeli officials insist they are not prepared to discuss American "compensation" for the Iran deal, saying that would imply acceptance of the accord. Israel believes there are loopholes in the deal that will pave the way for Iran to eventually emerge as a nuclear power.
Cabinet Minister Yuval Steinitz, Netanyahu's point man on the nuclear issue, told reporters "there is no real compensation for Israel" if Iran develops the capacity to make nuclear weapons. While he said that Israel will discuss "almost everything" with the U.S., he said Israel's focus right now is voicing its opposition to the deal.
The two countries have been holding talks on renewing a 10-year defense pact set to expire in 2018. Under the current deal, Israel receives about $3 billion in military aid from the U.S. each year. That number is likely to increase when the deal is renewed, and possibly before then.
Obama has indicated he is open to new ways of improving Israeli security, but he has played down the idea that ending economic penalties on Iran will drastically alter the balance of power in the region.
"Do we think that with the sanctions coming down, that Iran will have some additional resources for its military and for some of the activities in the region that are a threat to us and a threat to our allies? I think that is a likelihood," Obama told a White House news conference on Wednesday. "Do I think it's a game-changer for them? No."
Some private analysts also suggest the concern about Iranian ascendancy may be exaggerated.
"Naturally, with the lifting of sanctions there's going to be concern by Israel and Saudi Arabia that Iran will become 'normalized' in the region. However, I think Iran is still going to face a certain amount of isolation," Dalia Dassa Kaye, director of the RAND Center for Middle East Public Policy, wrote in an analysis.
Obama's principal military adviser, Gen. Martin Dempsey, met with Netanyahu and Israeli military officials just last month. The Joint Chiefs of Staff chairman told reporters with him in Israel that once an Iran nuclear deal was struck, Israeli and U.S. officials needed to "quickly and comprehensively" discuss the way ahead.
"It will be incumbent on both of us to make sure that we provide the kind of reassurances that the state of Israel has always counted on us to provide. But we are going to have to do the same thing with the Gulf allies," Dempsey said, alluding to deep concerns in Saudi Arabia and other Gulf states that removing sanctions on Iran would make it a greater regional danger.
Dempsey said he understands why Israelis believe a nuclear deal will give Iran room to accelerate its funding of surrogate Shiite groups like Hezbollah.
"I share their concern," Dempsey said.
