NEWS ANALYSIS : Inman Was Unprepared for Heat from Public Spotlight : Government: A career behind the scenes may have left the former defense nominee poorly equipped to deal with the world of politics.

Bobby Ray Inman’s bizarre withdrawal as the defense secretary nominee provides a glimpse into a peculiar Washington phenomenon--the insider who has spent so long behind the scenes that he is unprepared for the glare of the public limelight.

For more than 20 years, first as a Navy admiral and later as director of the National Security Agency and then deputy CIA director, Inman was part of a cadre of people who exercise great power in government but are insulated from the give-and-take of daily political life.

Inman’s remarks in announcing his withdrawal Tuesday and interviews with some of his friends suggest that the retired admiral was unequipped to step into the public arena. Despite his stated reasons, that lack of exposure to public life has emerged as the most plausible explanation for Inman’s abrupt turnabout.

“We thought: ‘He’s an insider--he probably knows the rules of the game.’ But he didn’t,” said Stephen H. Hess, a Brookings Institution political analyst. “We were all caught off guard by that.”

William Safire, the New York Times columnist accused by Inman of mounting unfair attacks, said Wednesday that he suspects Inman withdrew because he and other journalists were working on stories that might have damaged Inman’s chances for winning confirmation.

In his column appearing today, Safire wrote that Inman might have been worried by probes into reports that Inman had used a source on the Senate Intelligence Committee staff to help “manipulate” unsuspecting senators during Inman’s time at the CIA.

Inman had blamed a “new McCarthyism” in the press and the threat of a “partisan attack” by Republicans for his decision, but the media coverage and the GOP were overwhelmingly favorable toward him.

There were other ingredients as well: By Inman’s own admission, he did not thirst for the post. “I did not want a job in Washington,” he said in an interview.

He said he accepted Clinton’s offer because, as a career military officer, he found it difficult to refuse a presidential request.

Friends suggest that Inman’s longtime insecurities, apparently stemming from his days as a clumsy, bespectacled youngster, may have played a part by prompting him to overreact to fears that his reputation was being besmirched.

Inman’s experience is not unique in Washington politics. Others who have made the transition--notably Dwight D. Eisenhower, who went from five-star general to President, have had similar adjustments to make, although Eisenhower managed it more deftly.

Being an admiral or general provides a degree of insulation that often is a handicap for a would-be politician. Few are willing to criticize a senior military officer, especially in public.

And someone who has spent the bulk of his career as an intelligence officer is even more protected. By nature, the chiefs of the nation’s intelligence agencies stay in the background, even while advising presidents, briefing congressional leaders and influencing policies.

Especially during the Cold War, the bulk of their contact with the outside was behind closed doors--with lawmakers or reporters respectfully grateful for any morsel of information they were given.

Inman’s circumstances, and his own talents, accustomed him to receiving nothing but plaudits. Presidents, lawmakers and even the press praised him lavishly, extolling his brilliance and wisdom. Hardly an unkind word was to be found.

What Inman actually had to face during his few short weeks as defense secretary-designate was mild:

* A potential flap over his failure to pay Social Security taxes for a housekeeper peaked a few hours after it was announced, leaked by the White House to head off any serious brouhaha. The issue had been a major element in toppling two candidates for top Justice Department posts.

* News stories, backed up by bankruptcy records, noted his mixed performance in various business ventures. The articles were brought on mainly by Inman’s statements that he planned to bring more business techniques to government.

As Inman eventually admitted, the only real criticism came from a handful of columnists. News coverage and most editorials were heavy with praise; Inman said Tuesday that the working press had treated him fairly.

Inman did “more to besmirch his own reputation in his press conference than the press or the Republicans ever did,” Hess said. “Most people think his response bordered on the bizarre.”

Senate Minority Leader Bob Dole (R-Kan.), whom Inman accused--apparently without foundation--of spearheading a GOP attack against him, offered perhaps the unkindest cut of all:

“I think it’s probably a break for President Clinton that he didn’t get the job, the way he carried on yesterday,” the senator said Wednesday on CBS-TV’s “This Morning” program, in a view shared by some White House aides.
