In ikosmos' absence: "We need a stronger NATO to contain those sub-human Russians".
Well, yes, but in the original case, the dogwhistle was not intended to create a new desire in the listener, it was intended to appeal to an existing, very strong desire without actually mentioning it, because that desire was too scandalous when said out loud. In this case, it seems to me that there is no scandal in calling for a stronger NATO, and there is no strong, pre-existing desire for such a thing in the audience. Thus, whatever this political tactic might be, it does not seem to be a dogwhistle.
