It's like when they were teaching you about how to deal with the druggies in high school; Just say "No!" What part of we only trade one for one di you not understand? You have 24 hours to return our soldier or we will start bombing ALL your tunnels and terrorist schools. If you execute our soldier, we will hang one of your convicted murderer, belly-bombers. Just a few examples of how to say "No!" to terrorist hamasniks. Hamas is collectively like an eight year old; you can tell him "No!" but you usually have to tell him twice.
