In Israeli newspaper reportage of violence, the IDF "confirms", or "says", while the Palestinians "claim". The word "violence" itself connotes, according to Gershon Shafir, different events in Israeli and non-Israeli discourse: In the former, it is essentially dissociated from the 50 year long practice of occupying Palestinian lands and used to refer only to an intermittent recourse to military methods to contain episodic upsurges of hostile Palestinian resistance, a means employed when the security of an otherwise peaceful state is said to be at stake. Thus, Israeli violence is restricted to responses to specific events like putting down the First and Second Intifadas, Israel's wars in Gaza and the Palestinian knifing attacks in 2015–2016, which were mainly the work of lone wolves.
