Input: Ahmad Chalabi, the Iraqi politician who from exile helped persuade the United States to invade Iraq in 2003, and then unsuccessfully tried to attain power as his country was nearly torn apart by sectarian violence, died on Tuesday at his home in Baghdad. He was 71. 
  
 The cause was heart failure, Iraqi officials said. 
  
 Mr. Chalabi (pronounced CHAHL-a-bee) was the Iraqi perhaps most associated with President George W. Bush’s decision to invade Iraq and topple its longtime dictator, Saddam Hussein. 
  
 A mathematician with a Ph.D. from the University of Chicago, Mr. Chalabi, the son of a prominent Shiite family, cultivated close ties with journalists in Washington and London; American lawmakers; the neoconservative advisers who helped shape Mr. Bush’s foreign policy; and a wide network of Iraqi exiles, many of whom were paid for intelligence about Mr. Hussein’s government. 
  
 Mr. Chalabi’s relationship with the Americans stretched over decades. In 1998, he helped persuade Congress to pass the Iraq Liberation Act, which was signed by President Bill Clinton and declared it the policy of the United States to replace Mr. Hussein’s government with a democratic one. ||||| Ahmed Chalabi became White House favourite after providing information backing invasion of Iraq and toppling of Saddam Hussein 
  
 Ahmed Chalabi, the Iraqi politician who played a role in persuading the US to topple Saddam Hussein in 2003, has died of a heart attack, according to state television. 
  
 Haitham al-Jabouri, the secretary of parliament’s financial panel, which Chalabi had chaired, said attendants found him dead in his bed in his Baghdad home. 
  
 The Iraqi interior ministry issued a statement paying tribute to Chalabi’s work for the “salvation of the Iraqi people from dictatorship”. 
  
 Living in exile as head of the Iraqi National Congress (INC), which opposed Saddam Hussein, Chalabi became a White House favourite after he provided information that supported the US justification for invading Iraq in 2003. 
  
 But he lost favour after the invasion when much of his information regarding Saddam Hussein’s alleged possession of weapons of mass destruction and links to al-Qaida turned out to be false. 
  
 He was also accused of providing information to Iran. 
  
 Iraqi police and US forces raided his home in May 2004 and seized documents and computers, but the only formal charge Chalabi faced was putting forged banknotes into circulation after the raid turned up a small number in his home. 
  
 Chalabi was also dogged by allegations of corruption and was convicted by a Jordanian court of embezzling funds from the collapsed Petra bank in 1992, a case he claimed was politically motivated. 
  
 Born in October 1944 to a wealthy Baghdad family, Chalabi left the country in 1956 and spent most of his life in Britain and the US, where he received a doctorate in mathematics. 
  
 He organised a Kurdish uprising in northern Iraq in the mid-1990s in which hundreds of people were killed and he later fled, returning only when US-led invading forces took control. 
  
 Undaunted, he provided a steady stream of briefings that were used to bolster the case for the 2003 war, and his INC party provided a volunteer force that fought under US command during the invasion. 
  
 Key figures in US president George W Bush’s administration hoped Chalabi and the INC might take over Iraq as an interim government after the fall of Saddam. 
  
 But having spent many years outside Iraq, his group was little-known and little-liked at home. Plans for a smooth political transition fell apart, and instead Iraq was plagued by years of bloodshed. 
  
 Chalabi held the rotating presidency of the US-appointed Iraqi Governing Council after the invasion, served as deputy prime minister and also temporarily held the key oil portfolio, but he never reached the political heights to which he aspired. 
  
 Following the invasion, Chalabi, a secular Shia Muslim, was one of the main proponents of the “de-Ba’athification” drive to remove alleged Saddam supporters from public life, which alienated Iraq’s Sunni Arab minority and fuelled the revolt against US-led occupation forces. 
  
 Subsequent government policies further disenchanted Sunnis, and anger within the community ultimately laid the groundwork for Islamic State’s seizure of large parts of the country last year. ||||| BAGHDAD Ahmed Chalabi, the smooth-talking Iraqi politician who pushed Washington to invade Iraq in 2003 with discredited information on Saddam Hussein's military capabilities, died on Tuesday of an apparent heart attack. 
  
 Haitham al-Jabouri, secretary of parliament's financial panel that Chalabi had chaired, said attendants had found him dead in his bed in his Baghdad home. A news flash on Iraqi state television said the cause was a heart attack. 
  
 A secular Shi'ite, Chalabi rose to prominence as leader of the then-exiled Iraqi National Congress, which played a major role in encouraging the U.S. administration of former President George W. Bush to invade Iraq and oust Saddam. 
  
 "There are some people who will remember him in a good way, and there are others, to be honest, do not like and did not want his politics," said former prime minister Ayad Allawi. 
  
 "But regardless, Iraq lost a man who had an important contribution, important commitments towards the nation and he tried to offer what he could to this country." 
  
 Chalabi, born in 1944 into a wealthy Baghdad family, returned to Iraq shortly after Saddam's fall, the culmination of years of work abroad pressing and charming Washington to oust the man who ruled Iraq with an iron fist for decades. 
  
 He ultimately succeeded by persuading the United States that Saddam Hussein had links to al Qaeda and possessed weapons of mass destruction in the wake of the September 11 attacks, claims that later proved unfounded. 
  
 After the U.S.-led invasion of Iraq, he could often be seen in Baghdad flanked by dozens of bodyguards as he forged ties with political figures and powerful clerics. 
  
 CHECKERED CAREER 
  
 Once viewed in Washington as its preferred future Iraqi leader, he lost favor among his American benefactors amid accusations that he had passed information to arch-foe Iran. 
  
 “He pursued all roads in order to achieve a goal he believed in, which was overthrowing the oppressive regime of Saddam and build a civil state,” said Mithal Alusi, a secular lawmaker. “He followed any path possible, be it accepted or not.” 
  
 Chalabi was later charged with leading the purge of Saddam Hussein's Baath Party, a move that would prove costly. 
  
 Al Qaeda capitalized on the security vacuum that followed, triggering a sectarian civil war with attacks on the majority Shi'ite population that would plunge Iraq into chaos for years. 
  
 At one point, Chalabi's name was floated as a candidate for prime minister after he managed to skillfully navigate Iraq's Byzantine politics and forge alliances with the most powerful forces of the day. 
  
 But he never managed to rise to the top of Iraq's sectarian-driven politics. His fallout with his former American allies also hurt his chances of leading Iraq. 
  
 “Everyone was against him and accused him of being an agent, but they all secretly approached him and sought for him to be their bridge to the Americans,” said Alusi. 
  
 Chalabi's career was checkered. A former top banker, he was convicted of embezzlement by a court in Jordan and sentenced in absentia to more than 20 years in prison. 
  
 His tainted reputation never curbed his ambitions. 
  
 In the last few months, Chalabi had been working on an investigation into alleged irregularities in banking transactions in Iraq, a close associate told Reuters. 
  
 He held regular discussions about Iraq with academics, political supporters, friends and journalists who gathered at his home, styled after houses by American architect Frank Lloyd Wright and featuring a large swimming pool. 
  
 Senior politician Muwaffaq Rubaie, who said Chalabi was in good health when they last met over the weekend, described him as “a frighteningly intelligent guy”.

Output:
Ahmad Chalabi was once a US darling who was supposed to lead Iraq after the fall of Saddam Hussein. But with his death of a heart attack Tuesday at the age of 71, Chalabi's legacy is a much different one: He's now known mostly as the Iraqi figure who used faulty information about weapons of mass destruction to persuade the US to topple Saddam, reports the Wall Street Journal. It's unclear whether Chalabi himself knew the information was bogus. Here's how the New York Times puts it: "As it became clear that the evidence he promoted as proving that Mr. Hussein possessed weapons of mass destruction was, if not fabricated, then manipulated and exaggerated, the Bush administration distanced itself from him." The split became even more pronounced a year after the invasion when US forces invaded his home looking to prove accusations that he was spying for Iran. The only charges that resulted, however, involved forged bank notes, reports the Guardian. "There are some people who will remember him in a good way, and there are others, to be honest, [who] do not like and did not want his politics," former Prime Minister Ayad Allawi tells Reuters. "But regardless, Iraq lost a man who had an important contribution, important commitments towards the nation and he tried to offer what he could to this country." Chalabi was a member of Parliament at the time of his death.
