Professor Noam Chomsky, Sir Richard Dalton, Caroline Lucas, Ken Livingstone and others argue that the former UK prime minister is tainted by the war in Iraq. ● This Friday, 27 June, will mark the seven-year anniversary of Tony Blair's appointment as the Quartet representative to the Middle East. We, the undersigned, urge you to remove him with immediate effect as a result of his poor performance in the role, and his legacy in the region as a whole. We, like many, are appalled by Iraq's descent into a sectarian conflict that threatens its very existence as a nation, as well as the security of its neighbours. We are also dismayed, however, at Tony Blair's recent attempts to absolve himself of any responsibility for the current crisis by isolating it from the legacy of the Iraq war. In reality, the invasion and occupation of Iraq had been a disaster long before the recent gains made by the Islamic State of Iraq and Syria. The sectarian conflict responsible for much of the war's reprehensible human cost was caused in part by the occupying forces' division of the country's political system along sectarian lines. In order to justify the invasion, Tony Blair misled the British people by claiming that Saddam Hussein had links to al-Qaida. In the wake of recent events it is a cruel irony for the people of Iraq that perhaps the invasion's most enduring legacy has been the rise of fundamentalist terrorism in a land where none existed previously. We believe that Mr Blair, as a vociferous advocate of the invasion, must accept a degree of responsibility for its consequences.
