I can worry about Private Shalit, just as I can anyone else who briefly becomes a name and face from the Israeli-Palestinian conflict. Some demonize the entire IDF; however, in a nation with mandatory military service, demonizing the armed forces is the same as demonizing the entire population, and I know better than that. There are too many Israelis I like and respect for me not to give any one of them the benefit of the doubt. However, the way to stop this sort of situation is ulimately to work for a just end to the conflict, not calls for revenge and teaching the enemy a lesson.
UPDATE: The fact this post is the #10 google hit for (Corporal) Gilad Shalit is very strange. See this and this for my more complete thoughts on the situation.
