This longish piece offers a good discussion of how Israel has worked--with some success--to manage the narrative about the Gaza. As the piece reveals, what you seem to be seeing may not be what has actually happened. Israel's ability to manage the news is enhanced by its barring of international media from Gaza. As a result, more or less independent news sources are unable to provide readers and viewers a sense of what is really happening on the ground.
