Whose naive? Remember Trotskii and crowbar?
As I said, this is nothing new, and you proved my point by referring to an incident from over half a century ago. Plenty acts of assasination and sabotage have happened over millenia. Nothing new.
Since soviet times the assasinations abroad diminished somehow.
Makes sense. Cold war is over. One would expect that as hostilities die down so does espionage, etc.
But if that practise are now blessed by Israel the honorable member of civilized community then it may surge again.
As conflicts surge so do assasinations. The biggest recent conflict was the Cold War. As you said, as that ended "the assasinations abroad diminished somehow.". The next biggest conflict is the West vs fundamentalist Islam. One would expect the assasinations,etc. to surge. Would you agree? Funny how you don't mention Syrian/Iranian death squads (Hizbollah) or palestinian Fatah/Hamas. Why should Israel fight with one arm behind its back?
