Hamas maintained a ceasefire from June 2008. Israel as usual did not keep it's side of the bargain by opening the crossings. It smashed the ceasefire on the night Barak Obama was elected by assassinating 6 Hamas people in Gaza. Israel did this as a prelude to launching Cast Lead to destroy the infrastructure of Gaza and anyone and everyone who got in the way. Who knows what Israel's endgame is. Probably to force all the people of Gaza into Egypt - then it will have the land without the people.
