1. Doesn't Europe believe a threat against one is a threat against all.

IMHO, They need to notify the US formally that any further threats are to be considered hostile in nature and swift actions from Europe as a whole will be forthcoming. Then lay out the details of escalating actions. Demand the administration refrain from further threats.
I know it sounds simple but the Felon needs somebody to wake him up to reality.
Or, let him know, he's no threat and considered to be just an annoyance.
