It was clumsy phrasing, I will agree. However, even as phrased, it doesn’t refer to a literal copy of the same act, in the same way that an abuser reenacting their childhood abuse will not literally copy each element of that abuse play-by-play. The reenactment of trauma refers to reproducing any of the actions, behaviours or relationship patterns associated with that trauma in subsequent situations or relationships. The argument (not my argument, I’m just noting that the argument exists) would be that for the Israelis to visit genocide on this low-power group that they have at their mercy is very much of the same pattern as what the Jews experienced at the hands of the Nazis.
