That is EXACTLY the point, you liars claim they are deprived of food, medicine and other goods and you repeat it over and over.
It is infact one of the claims of the supposed freedom flotilla. All it is is a bunch of LIES.
From the beginning, the Flotilla organizers have said publicly that their purpose is to break the blockade, which has completely destroyed the economy and infrastructure of Gaza.
The ships were not bringing food (except for a few chocolates and such) - they were loaded with primarily building supplies and medical equipment.
Gaza's water, electricity and sewage facilities have been extensively damaged by Israeli bombing. The blockade prevents them from being rebuilt. It prevents people from being able to rebuild their homes and their hospitals. It prevents people from running their businesses; to export their agricultural products (a major part of Gaza's industry.) It leaves them utterly dependent on international aid for food.
The blockade of Gaza has failed on every single one of the Israeli government's stated objectives. It has not forced Hamas from power. It has not turned Gazans against Hamas. It has not stopped rockets into Israel. And it has not forced the release of Gilad Shalit.
Israel's blockade has accomplished nothing other than to devastate the lives of 1.5 million people, and cause world opinion of Israel to plummet and increase its international isolation. And it shot itself in the foot again with the Flotilla raid.
I think a lot of Americans do not follow Israeli news very much, or they would see that there is a huge internal debate among Israelis themselves over this very subject. A significant number of Israelis from various sectors of society - military, political, academic, journalism - are loudly urging their government to abandon the failed policies that actually harm Israel's interests.
