What can I say, but... what evil kassams...
The first headline gives the impression that the Kassams are the aggressors. The Kassams seem to be attacking from the wording in the headline.
The second two headlines are written in passive tense, alluding to "some other force" controlling the kassams. But its identity is kept secret.
Amazingly, it's davka the extreme Left-wing paper, Ha'aretz, which is the only one to give a "hint" as to who the aggressor is:
OK, they don't use the "t" word. They just couldn't say "Arab terrorists, and they don't call them "Palestinians," either, even though they, unlike yours truly, call the Arabs that. They just would never admit that their "peace partners" are really attacking Israel.
We can't defeat our enemy until we recognize who it is. And we won't have peace until we defeat our enemy!
