It's pretty standard for novelty accounts to put disclaimers in their details, so I don't think that provides much information one way or another.

Oh, I interpreted the "not a novelty account" option to be "actually Henry Kissinger", which that disclaimer means it probably isn't.

Yeah, my post was underconstrained. I meant to consider possibilities 1 and 2:

    1. Parody role-play of Henry Kissinger ("novelty")
    2. Unironic tribute to Kissinger in the username
    3. Actually Henry Kissinger
