PARIS â More than a decade before the international agency that monitors chemical weapons won the Nobel Peace Prize, John R. Bolton marched into the office of its boss to inform him that he would be fired.
âHe told me I had 24 hours to resign,â said José Bustani, who was director general of the agency, the Organization for the Prohibition of Chemical Weapons in The Hague. âAnd if I didnât I would have to face the consequences.â
Mr. Bolton, then an under secretary of state and later the American ambassador to the United Nations, told Mr. Bustani that the Bush administration was unhappy with his management style.
But Mr. Bustani, 68, who had been re-elected unanimously just 11 months earlier, refused, and weeks later, on April 22, 2002, he was ousted in a special session of the 145-nation chemical weapons watchdog.
The story behind his ouster has been the subject of interpretation and speculation for years, and Mr. Bustani, a Brazilian diplomat, has kept a low profile since then. But with the agency thrust into the spotlight with news of the Nobel Prize last week, Mr. Bustani agreed to discuss what he said was the real reason: the Bush administrationâs fear that chemical weapons inspections in Iraq would conflict with Washingtonâs rationale for invading it. Several officials involved in the events, some speaking publicly about them for the first time, confirmed his account.
Mr. Bolton insists that Mr. Bustani was ousted for incompetence. In a telephone interview on Friday, he confirmed that he had confronted Mr. Bustani. âI told him if he left voluntarily we would give him a gracious and dignified exit,â he said.
As Mr. Bustani tells the story, the campaign against him began in late 2001, after Iraq and Libya had indicated that they wanted to join the Chemical Weapons Convention, the international treaty that the watchdog agency oversees. To join, countries have to provide a list of stockpiles and agree to the inspection and destruction of weapons, as Syria did last month after applying. Inspectors from the agency were making plans to visit Iraq in late January 2002, he said.
âWe had a lot of discussions because we knew it would be difficult,â Mr. Bustani, who is now Brazilâs ambassador to France, said Friday in his embassy office in Paris. The plans, which he had conveyed to a number of countries, âcaused an uproar in Washington,â he said. Soon, he was receiving warnings from American and other diplomats.
âBy the end of December 2001, it became evident that the Americans were serious about getting rid of me,â he said. âPeople were telling me, âThey want your head.â â
Mr. Bolton called on Mr. Bustani a second time. âI tried to persuade him not to put the organization through the vote,â Mr. Bolton said.
But still Mr. Bustani refused, and his fate was sealed. The United States had marshaled its allies, and at an extraordinary session, Mr. Bustani was ousted by a vote of 48 to 7, with 43 abstentions. He was reportedly the first head of an international organization to be pushed out of office this way, and some diplomats said the pressure campaign had made them uneasy.
Mr. Boltonâs office had also circulated a document that accused Mr. Bustani of abrasive conduct and taking âill-considered initiativesâ without consulting with the United States and other member nations, diplomats said.

But Mr. Bustani and some senior officials, both in Brazil and the United States, say Washington acted because it believed that the organization under Mr. Bustani threatened to become an obstacle to the administrationâs plans to invade Iraq. As justification, Washington was claiming that Saddam Hussein, the Iraqi leader, possessed chemical weapons, but Mr. Bustani said his own experts had told him that those weapons were destroyed in the 1990s, after the Persian Gulf war.
âEverybody knew there werenât any,â he said. âAn inspection would make it obvious there were no weapons to destroy. This would completely nullify the decision to invade.â
Mr. Bolton disputed that account. âHe made that argument after we invaded,â he said. Twice during the interview, Mr. Bolton said, âThe kind of person who believes that argument is the kind who puts tin foil on his ears to ward off cosmic waves.â
But diplomats in The Hague said officials in Washington had circulated a document saying that the chemical weapons watchdog under Mr. Bustani was seeking an âinappropriate role in Iraq,â which was really a matter for the United Nations Security Council.
Avis Bohlen, a career diplomat who served as Mr. Boltonâs deputy before her retirement, said in a telephone interview from Washington on Saturday that others besides Mr. Bolton believed that Mr. Bustani had âstepped over some linesâ in connection with Iraq and other matters. âThe episode was very unpleasant for all concerned,â she said.
Speaking from São Paulo, Brazil, on Saturday, Celso Lafer, the former Brazilian foreign minister, said that in early 2002, he was asked to meet privately with Secretary of State Colin L. Powell, who a year earlier had praised Mr. Bustaniâs leadership in a letter.
Mr. Lafer said Mr. Powell told him, â âI have people in the administration who donât want Bustani to stay, and my role is to inform you of this.â â
âIt was a complicated process,â Mr. Lafer recalled, âwith the United States and particularly John Bolton and Donald Rumsfeld wanting the head of Bustani.â
âMy view,â he continued, âis that the neocons wanted the freedom to act without multilateral constraints and, with Bustani wanting to act with more independence, this would limit their freedom of action.â
Getting Mr. Bustani fired took some doing. Washington failed to obtain a no-confidence motion from the chemical weapons watchdogâs executive council. Then the United States, which was responsible for 22 percent of the agencyâs budget at the time, threatened to cut off its financing and warned that several other countries, including Japan, would follow suit, diplomats have said.
Mr. Bustani recalled that the ambassador from Britain, one of the agencyâs most committed member nations, told him that London had sent instructions to vote with Washington. With the United States and Japan covering almost half the budget, the organization ran the risk of collapsing, Mr. Bustani said.
On Friday, while fielding a flow of messages in his office, Mr. Bustani said he felt gratified about the Nobel Prize news and did not regret his days at the agency. âI had to start it from the beginning, create a code of conduct, a program of technical assistance,â he said. âWe almost doubled the membership.â
He reflected on the contrast between Iraq and Syria. Inspectors from the agency are there now, cataloging the governmentâs stockpiles of chemical weapons as a step forward in Syriaâs civil war, now in its third year.
âIn 2002, the U.S. was determined to oppose Iraq joining the convention against the weapons, which it did not even have,â he said. âThis time, joining the convention and having the inspectors present is part of the Syrian peace plan. It is such a fundamental shift.â
