the seige against 1.5 million people has nothing to do with the SINGLE prisoner of war Hamas is keeping. and the SINGLE crossing into Egypt has only been closed once during a holiday weekend since Israel's pirate ship fiasco. Also, while the siege has been decreed illegal by countless international bodies (including many in Israel's only ally, the US), the taking of a POW is not illegal (and neither is not letting the Red Cross see him, since Hamas is not a country nor a signatory to the Geneva Conventions.) you'll recognize this defense as "This is why Israel doesn't have to say whether it has nuclear weapons. They never signed the NPT."
