aggressor, n.All

An Aggressor (n.) is, ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠as Justice Jackson told Nuremberg, the first state to invade another — or to arm and shelter bands that attack it.

Aggressor (n.) recasts ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠himself after the war as the injured party: the unresolved problem is what they did to us.
