U.S. Set to Offer Huge Arms Deal to Saudi Arabia

WASHINGTON, July 27 — The Bush administration is preparing to ask Congress to approve an arms sale package for Saudi Arabia and its neighbors that is expected to eventually total $20 billion at a time when some United States officials contend that the Saudis are playing a counterproductive role in Iraq.

The proposed package of advanced weaponry for Saudi Arabia, which includes advanced satellite-guided bombs, upgrades to its fighters and new naval vessels, has made Israel and some of its supporters in Congress nervous. Senior officials who described the package on Friday said they believed that the administration had resolved those concerns, in part by promising Israel $30.4 billion in military aid over the next decade, a significant increase over what Israel has received in the past 10 years.

But administration officials remained concerned that the size of the package and the advanced weaponry it contains, as well as broader concerns about Saudi Arabia’s role in Iraq, could prompt Saudi critics in Congress to oppose the package when Congress is formally notified about the deal this fall.

In talks about the package, the administration has not sought specific assurances from Saudi Arabia that it would be more supportive of the American effort in Iraq as a condition of receiving the arms package, the officials said.

The officials said the plan to bolster the militaries of Persian Gulf countries is part of an American strategy to contain the growing power of Iran in the region and to demonstrate that, no matter what happens in Iraq, Washington remains committed to its longtime Arab allies. Officials from the State Department and the Pentagon agreed to outline the terms of the deal after some details emerged from closed briefings this week on Capitol Hill.

The officials said Secretary of State Condoleezza Rice and Defense Secretary Robert M. Gates, who are to make a joint visit to Saudi Arabia next week, still intended to use the trip to press the Saudis to do more to help Iraq’s Shiite-dominated government.

“The role of the Sunni Arab neighbors is to send a positive, affirmative message to moderates in Iraq in government that the neighbors are with you,â€
