Wasn't the Operation Wrath of God conducted by Israel after the Munich massacre a similar event?
I think there was only some international outrage after they killed the obviously wrong man(out of many more assassinated), so the precendent has been set up much earlier.
Or maybe more pointedly, Operation Opera, where Israeli planes flew through Saudi airspace to bomb an Iraqi nuclear power plant (full of French technicians). The pertinent element here being the Saudi airspace; Israel and Saudi Arabia may not be "allied" in any meaningful sense (in 1976 that is), but they were in a stable peace and mutually allied in some way to essentially all of NATO. Which doesn't even get into the extremely dubious "threat" posed by a civilian nuclear reactor in Iraq manned and administered by the French. It instantly earned Israel the ire of basically every diplomatic body, including a resolution of condemnation from the UN, for being a gross violation of international sovereignty and any sense of a "due process" of war, for lack of a better term.
Of course, being Israel, nobody remembers or cares or made any attempt to actually punish them for the action, except states that would want to punish Israel for existing at all. Still a comparison though.
