Motives behind Gaza Blockade

Here is an interesting article from the AP that hasn't gotten much play. Most telling, regardless of whether there actually is a sinister Israeli document is an Israeli official stating that authorities will continue to ease the blockade but "could not lift the embargo altogether as long as Hamas remains in control" of Gaza. This quite nearly suggests the blockade as means of pushing Hamas out of power, clearly falling in line with the idea of a "limited economic war": Punishing civilians as a means of attacking Hamas. What the article also illuminates is the extent of all that is restricted now in Gaza: Up until two weeks ago soda, juice, jam, spices, shaving cream, potato chips, cookies and candy were all prohibited.
