President Barack Obama announced Osama bin Laden's death shortly before midnight on May 1, 2011 during a televised appearance in the East Room of the White House.
"The death of bin Laden marks the most significant achievement to date in our nation's effort to defeat al Qaeda," Obama said.
Yet five years later, militant Islamic extremism has hardly receded, according to NBC News' analysis. There have been three important developments since bin Laden's death.
ISIS has surged onto the international stage two years ago with a series of mass executions, beheadings and enslavement. Al Qaeda's core may have lost significant ground in Pakistan, but experts worry that the group's affiliates in Yemen and Syria are poised for a comeback. Obama meanwhile, is still trying to close the prison facility at the U.S. Naval Station Guantanamo Bay in Cuba since before Bin Laden's death, arguing that it's "one of the key magnets for jihadi recruitment."
