Maybe not all but most of them probably. May I interest you in the sinking of the Rainbow Warrior by the French goverment? It was codenamed: Opération Satanique, and was an act of French state terrorism.
Probably everybody who was involved in that operation is now retired or dead. That bit of history is now at least middle-aged (I'd say verging on old, but I've recently been informed on HN that what I consider old is middle aged otherwise my fellow olds get sad), we're two generations away, so if we do accept it as proving your point - for how much longer would you accept it as relevant?
Probably the ones we do not know about are worse.
