So at what point do we call this a domestic Islamist terror attack?

Oh, right. That’s scheduled for the Fifth of Never, as S.M. Stirling might say.

They’ll go with ‘lone wolf,’ which has the ‘advantage’ of being technically accurate while ignoring that groups such as ISIS have been looking for suitable ‘lone wolves’ for some time now. …And this is the point where the conversation gets tangled up and people end up glaring at each other, so let me just say that we will not resolve the problem until we admit that there is a problem. And by ‘we’ I mean ‘the current administration.’
