What can we do? We are civilized and they are not. We care about our soldiers and their families.

No, I'm afraid you do not. If you cared, then you would have a death penalty for people like Kuntar, so that they too can be released in caskets. And if you cared, you would be intelligent enough, seeing our soldiers brought back to us dead, to have put a bullet through Kuntar and then turned him over to his friends.

If we cared about our soldiers, we would not be showing our enemies that kidnapping and terrorism pay. We would not be setting the stage for the next murderous terrorist raid and hostage standoff. We would be passing laws with a mandatory death penalty for convicted terrorists with blood on their hands, as well as their accomplices. We would be making these laws retroactive. Then, we would be cutting off all water and electricity to Gaza until Gilad Shalit is released. If that didn't work, we'd begin executions within one week, increasing the number convicted terrorists facing firing squads with each passing day until Gilad is returned to us safe and sound. And if that didn't work, we would begin daily bombings of Gaza, with the same number and frequency of attacks that our own city Sderot has suffered over the past three years from the Gazans. Not civilized? Perhaps. But moral. Extremely moral.
