Sometimes, the way that international sophisticates think makes itself very, very plain.
Let's review: Israel withdrew from the Gaza Strip a long time ago. That many ISM activists don't know this doesn't make it less true. Until about... oh... 24 hours from now, there hadn't been a significant Israel military presence in the Gaza Strip for years (a single raid notwithstanding). Today's attack occured on Israeli soldiers in an Israeli base on internationally recognized Israeli territory. So you wouldn't think that respectable news outlets would describe it as a "Gaza attack":

They write this way so that they can continue pretending that Palestinians are murdering Israelis because of the Occupation. Rather than, say, because they like to murder Israelis. Over 1,000 articles isn't just carelessness - it's evidence of an unseemly, engrained mentality. A mentality that is the result of conditioning meant to excuse every sort of Palestinian atrocity as an "understandable reaction to the Occupation".
It was not a Gaza attack. It was an attack that happened in Israel.
