The killing of Bin Laden will certainly remain a defining moment in Obama's presidency, if for all the wrong reasons, says Anayat Durrani Details continue to surface on an assassination mission President Barack Obama called "the longest 40 minutes of my life". In his interview Sunday on "60 Minutes" President Obama reaffirmed that "Justice was done," and added anyone who didn't think Bin Laden deserved it "needs to have their head examined". According to a new NBC poll, 80 per cent of Americans said it was the right decision to kill the Al-Qaeda leader rather than capture him. A survey by the Pew Research Center for the People & the Press and The Washington Post found that 60 per cent feel "proud" and even "happy". Obama took part in a ceremony at Ground Zero, laying a wreath at the site where the World Trade Centre once stood. After the ceremony, Obama met with 60 family members of 9/11 victims during a private session. As if to address bruised Pakistani feelings, he chatted with Pakistani-American Talat Hamdani, whose son Salman died while trying to rescue victims when the World Trade Center collapsed on 9/11. In the immediate aftermath of the attacks, her son was wrongly believed to be involved with the terrorists, until his remains were discovered six months later in the rubble along with his medical bag. Hamdani said she greeted the president with Asalamu alaikum to which he responded wa alaikum asalam, and said she "thanked him as a mother for bringing this man to justice." She called the experience "a healing moment" . The ceremony was meant to bring closure but looked suspiciously like the early public launching of Obama's re-election campaign. Only 30 per cent believe the economy will improve in the next year, which would be sure to leave Obama at sea in next year's election campaign. As if to counter his low ratings on economic matters, his killing of Bin Laden convinced Americans that he is a strong leader and a good commander in chief, and public opinion for his handling of the war in Afghanistan increased to an all-time high. Since the raid, there have been calls for the release of photographic proof of Bin Laden's death to quell sceptics and conspiracy theorists -- half of Americans want more solid proof. Washington's refusal so far to divulge much information that is believable is frustrating. National Security Advisor Tom Donilon added to the frustration by bragging that materials seized from Bin Laden's compound were the largest cache of terrorist intelligence ever gathered, describing it as a "treasure trove" of data. While Americans were overall happy about Bin Laden's killing, one group of Americans has been outspoken about their distaste for the use of code name "Geronimo" for the US operation that killed Bin Laden. "Geronimo EKIA" (enemy killed in action) was the message US Navy SEALs used to notify Washington officials that the mission was completed. But the code name angered many Native Americans because Geronimo is the name of a Native American warrior many consider a hero. They said equating him with Bin Laden is an insult to all Native Americans. Some have called for a public apology from Obama. The administration has not commented on why the operation chose the name of Geronimo, saying the selection process of code names for missions such as the one targeting bin Laden -- like the proof that Bin Laden was killed, is confidentiall
