There is enough evidence that, while not directly performing attacks, they have considered doing such and engage in behaviors that encourage such attacks. For example, look at the FBI radicalizing individuals and convince them to carry out attacks. Even though the FBI works to make the actual attack a fake, they have created a dangerous individual who may switch to carrying out an attack. And this isn't even considering the things the CIA has done. I see no reason why the US would be alone in these horrors.
