From what I hear:

a) Thousands of rockets have been fired into Israel by Hamas
a1) However, these thousands of rockets were mostly home-made and not awfully lethal

b) The Israeli Supreme Court has ruled that journalists should be allowed into Gaza
b1) However, the Government of Israel has refused to allow journalists in

c) A third of all the 1,000+ dead are children

d) Gaza has a population of a million crammed into an area around the size of the Aran Islands

e) There are other methods of making people stop hating you than killing them
