Days later, there's reason to wonder how zealously the administration will work to uncover everything that needs to be known.
The day after the Sept. 11, 2012, Benghazi, Libya, attacks, which left four Americans -- Ambassador J. Christopher Stevens, Sean Smith, Tyrone Woods and Glen Doherty -- dead, Obama made a similar statement. "Make no mistake," the president said. "We will work with the Libyan government to bring justice to the killers who attacked our people."
More than seven months later, there have been no indictments and no arrests. According to a House Republican Conference report on the Benghazi attacks released Tuesday, the FBI investigation into the attacks has yielded "very little progress." The GOP leaders questioned why the administration chose to put the FBI in charge of the investigation when the FBI team did not have access to the Benghazi crime scene for three weeks. You might think that the administration didn't want quick answers.
Washington ordered criminal investigations after the 1998 U.S. Embassy bombings in Nairobi, Kenya, and Dar es Salaam, Tanzania, and the 2000 attack on the Navy destroyer Cole. The GOP leaders observed at the time that those probes did not deliver the full weight of justice.
The Obama administration is one that clings to the fiction that the 2009 Fort Hood, Texas, shootings, which left 13 dead, were not a terrorist attack but "workplace violence."
After Benghazi, U.N. Ambassador Susan Rice went on the Sunday TV talk shows to blame the violence on an anti-Islam video, which allegedly spurred a protest that then was "hijacked" by armed extremists, when the administration clearly knew better.
I'm not blaming the Obama administration for the attack in Boston or the one in Benghazi. Terrorists are responsible for the carnage. I blame the administration for not acting decisively after Benghazi, as I hope for a better response after Boston.
I do understand why the president hesitated before calling the Boston bombings an "act of terrorism." I believe that authorities are right not to charge surviving suspect Dzhokhar Tsarnaev, 19, as an enemy combatant; he is a U.S. citizen.
