|The Wikispooks article concentrates on details omitted from the corresponding Wikipedia page.
1) Missing from the Wikipedia article is the well-referenced story of how Israel deliberately put tons of explosives into the hands of Gazan militants - against the wishes of Hamas and over the protests of international observers.
2) Missing from the Wikipedia article is the controversy when the BBC refused to broadcast a humanitarian appeal.
3) Well-known at the time but since almost completely forgotten is that Hamas had cut rocket fire by 99.5% before Israel broke the 6-month ceasefire (the Wikipedia largely uses the Zionist narrative by which it was a "lull").
Wikispooks takes the view that international reports (3 from the UN, one each from Human Rights Watch (HRW) and Amnesty) are likely to be the most important sources for the factual content of an honest, balanced article, while non-participating sources (eg newspaper reports) are the second most valuable source. Reports direct from the participants are likely to be the least reliable. Sources known to be ideologically linked to one side or the other are to be used only with care.
(Note - the Wikispooks article follows the Wikipedia and uses the Israeli designation "Operation Cast Lead", rather than the more neutral "Gaza War").
