By your logic, it's acceptable for the PM of Italy to order the assassination of an Italian-American dual citizen because that Italian has pledged allegiance to a foreign state that engages in violence?
If that dual citizen is actively engaging in such violence and Italy is a (potential) target of such violence, and his activities are happening outside Italy, yes.
> "Where high-level government officials have determined that a capture operation is infeasible and that the targeted person is part of a dangerous enemy force and is engaged in activities that pose a continued and imminent threat to US persons or interests."
