Yep, I’d say that qualifies as a threat.

I’m not sure that qualifies as a threat though saying “with my bare hands” does suggest the means to do it. If he said “I want to blow you up with a hellfire missile” that would be near impossible - unless he had a hellfire missile. Threat, motive, and means are, afaik, all part of what constitutes a legitimate threat.
