WASHINGTON (AP) – Bitter divisions over the Iraq war, particularly on Capitol Hill, led the Bush administration to change course and replace General Peter Pace as chairman of the Joint Chiefs of Staff, a grim Secretary of Defense Gates said Friday.

Mr. Gates said that despite earlier plans to recommend General Pace for a second two-year term as chairman, he instead was recommending Admiral Mike Mullen, currently chief of naval operations, to take over when General Pace’s term expires Sept. 30. President Bush accepted the recommendation.

“I think that the events of the last several months have simply created an environment in which I think there would be a confirmation process that would not be in the best interests of the country,” Mr. Gates said. “I wish it were not necessary to make a decision like this. But I think it’s a realistic appraisal of where we are.”

Mr. Bush praised General Pace, saying he has “relied on his unvarnished military judgment, and I value his candor, his integrity, and his friendship.”

“Pete’s job has been to help ensure that America’s military forces are prepared to meet the threats of this new century,” Mr. Bush said in a statement issued in Rome, where he is visiting. “This is a difficult task in a time of peace. Pete Pace has done it in a time of war – and he has done it superbly.”

Mr. Gates said he had been told by Republican and Democratic senators that a confirmation hearing for General Pace would be a “backward-looking and very contentious process.”

Senatorl Levin, Democrat of Michigan, acknowledged such advice, saying he had gathered views from a broad range of senators. “I found that the views of many senators reflected my own,” and confirmation would have focused on the past four years of war, he said.

A spokesman for Senator Clinton, Democrat of New York, said she, too, believed it would have been a difficult renomination.

“When it comes to Iraq it’s not enough for President Bush to change the cast, he must also change their script,” said the spokesman, Philippe Reines.

Admiral Mullen has long been eyed for a promotion, and on Friday Mr. Gates praised him as having the “vision, strategic insight and integrity to lead America’s armed forces.”

The announcement still seemed to surprise some senior Pentagon officials who as recently as last week were convinced there would be a second term for General Pace, the first Marine to serve as chairman of the Joint Chiefs. Pace will now retire when his term is up at the end of September.

General Pace’s departure will put nearly an entirely new slate of leaders and military commanders in charge of the war, which is now in its fifth year and has claimed the lives of more than 3,500 U.S. troops.

Secretary of Defense Secretary Rumsfeld abruptly resigned a day after last year’s elections, which were consumed with debate on the war and swept Democrats into control of Congress.

Since then, the Democrats have shown an eagerness to challenge President Bush’s handling of the conflict and support among Republicans has waned as well.

Mr. Gates made it clear his decision on General Pace came reluctantly.

“I am no stranger to contentious confirmations, and I do not shrink from them,” Mr. Gates said. “However, I have decided that at this moment in our history, the nation, our men and women in uniform and General Pace himself would not be well served by a divisive ordeal.”

Democrats have used recent military confirmation hearings, including one earlier this week, to blast the administration’s handling of the war.

Senate Majority Leader Senator Reid said senators, “will be looking very closely at Admiral Mullen and General Cartwright’s views to make sure they are committed to changing course in Iraq. Both men must be advocates for our troops, not for a failed policy.”

White House spokesman Gordon Johndroe said Mr. Gates “informed the president a little over two weeks ago that consultations had not gone well (with senators) and it was his recommendation that we not go forward with the renomination of General Pace.”

Mr. Gates called Mr. Bush’s national security adviser, Steve Hadley, in Heiligendamm, Germany, Thursday night, to talk about the timing of the announcement, and on Friday Mr. Hadley informed Mr. Bush that they were going forward. “The president had already concurred” based on the earlier talks with Mr. Gates, said Mr. Johndroe, who was traveling overseas with Mr. Bush.

Asked whether the developments indicated GOP support for the war was waning, Mr. Gates said, “No, I don’t think it says that.”

As chairman of the Joint Chiefs of Staff for two years, and vice chairman for the previous four, General Pace has been involved in all of the key decisions leading to the 2002 invasion of Iraq and the planning for the post-Saddam Hussein era.

Mr. Johndroe said, “He is an example for all our men and women in uniform and has been an integral part of the president’s national security team.”

General Pace had stirred controversy recently by saying that homosexuality arts are immoral and the military should not condone such behavior by allowing gays to serve openly. He later said he should not have expressed his personal views and should have simply expressed his support for the military’s “don’t ask, don’t tell” policy, which allows gays to serve if they keep their sexual orientation private.

Admiral Mullen was in Annapolis at the Naval Academy on Friday when the announcement was made. His spokesman, Commander John Kirby, issued a statement saying Admiral Mullen was honored.

Mr. Gates said Mr. Mullen “has a broad view of what the needs and requirements of the services are.” To illustrate that, Mr. Gates said that when Admiral Mullen was recently asked by senior Pentagon adviser what he was most concerned about, he replied, “The Army.”

The Army has been strained to the breaking point by soldiers’ lengthy, repeated and difficult tours in the Iraq and Afghanistan wars.

Mr. Gates also heaped praise on General Pace, who recently celebrated his 40th year as a Marine. “He has served our country with great distinction and deserves the deepest thanks of the American people for a lifetime of service to our country and for his leadership. I have thoroughly enjoyed working with him, trust him completely and value his candor and his willingness to speak his mind,” he said.

Mr. Gates said he would recommend General James E. Cartwright, currently the commander of the Strategic Command, to be vice chairman of the Joint Chiefs of Staff. He would succeed Admiral Ed Giambastiani, who is retiring. Mr. Bush said he would also accept that recommendation.

The defense secretary said he had originally intended to name Admiral Giambastiani to a second two-year term, but Admiral Mullen’s selection had foreclosed that possibility. Mr. Gates then offered Admiral Giambastiani another senior assignment, but the admiral declined the job. It is customary for the chairman and vice chairman to come from different branches of the service.

Other members of Congress were largely mum about the discussions with Mr Gates prior to the announcement, preferring to offer praise for both General Pace and Admiral Mullen.
Senator Warner, Republican of Virginia, said General Pace had served with “the greatest of distinction.” He added, “As we look to the future, in Admiral Mullen, we will have a new hand on the helm, a steady, well-trained hand that will guide and protect the men and women of all of our services, and their families.”
