They are not starving to death or dying because of a lack of medicine in Gaza. Israel lets all that through and more it just has to be done through official bodies like the UN rather than direct to ensure it does not end up in the hands of Hamas. Construction materials etc are also allowed in but again through official origanizations so it doesn't end up being used to line smuggling tunnels. People can go in and out of Gaza via Raffah so they are not all trapped in a prison they cannot leave. What israel is doing is operating a legitimate sea blockade to make sure no weapons get into Gaza to be used against Israel. These flotilla's are about breaching the blockade for political purposes and the aid cargo is the justification of these cruises. If it was about humanitarian aid then they would accept Israel's offer to dock in Ashdod or even Egypt, have their cargo inspected see if there is anything in it thats banned and then deliver it overland. The organisers of these cruises don't give a damn about humanitarianism all they care about is the political cause and they expect and want Israel to refuse the ships to reach Gaza because its good PR for them. Assuming this flotilla is entirely peaceful we can't let it dock because we let this one through another will come and another and another and eventually a ship will come along whose cargo is not medicines but weapons ... remember the Karine A? When the palestinians end the terror Israel will end the blockade but the palestinians can't have it both ways.
