"Really, how much ability does Zawahiri have if his message to commemorate his organization's biggest success doesn't get out until the day after the event?" Watts said.
Zawahiri also said, "The Boston incident confirms to the Americans the extent of their lying and tricking of themselves, and their arrogance from accepting the truth that is as bright as the sun, which is that they are not facing individuals, organizations or groups but they are facing an uprising... Al Qaeda was a message before it was an organization."
Dick Clarke, former White House counter-terrorism advisor and ABC News consultant said, "It sounds like he knows that the only thing likely to happen are small scale and loan wolf attacks, so he encourages them in order to claim some credit if they occur."
"It is revealing that the leader of Al Qaeda seems to be suggesting he has no reach to execute an attack inside the U.S.," Watts told ABC News, "and is essentially saying that he's hoping someone will just volunteer and accomplish his goals for him."
