Noam Shalit, father of captive Israeli soldier Gilad Shalit, told CNN he offered through his lawyer to attempt to convince the Israeli government to let the flotilla arrive in Gaza if participants would pass aid, including letters and medicine, to his son. The organizers of the convoy, including Berlin, refused, he said, telling him their main purpose is to break the siege.
This is highly indicative. To bring along letters and aid to Shalit is essentially a cost-free move by the convoy participants. It would signal nothing more than that its concern for human rights is universal, rather than particular only to when Israelis are wronging Palestinians (and not a particularly strong signal at that). And yet, they refused, because apparently it would distract from their "main purpose". I don't see how a proposal which would have made it more likely the convoy would reach Gaza shores would be in conflict with "breaking the siege", but I do see how such a proposal would distract from a main purpose of highlighting Israeli depravity and Palestinian innocence.
Oh, go to hell already. It's amazing how few people examining this conflict have a universal and principled concern for human rights and human dignity.
And also, I might add, the Israeli government claims it is perfectly willing to allow the goods into Gaza, so long as they are checked for security threats at an Israeli port. This probably isn't quite as one-sided as it sounds -- the convoy is bringing in construction materials, which Israel has been classifying as a security threat (one can use construction materials to construct bunkers), but it is meaningful information.
