Its a no-brainer. Hamas does not value the human life the way Israelis do. To them 450 blowing themselves up is acceptable as long as Israeli civilians are also hurt. Any talk of cease-fire from Hamas is a ploy to stop effective IDF operations and to re-arm. It will only give them time to plan more terror attacks to provoke IDF response. Keep the pressure on Hamas and do not release the terrorists. It didn't work with Hezbollah and it will not work with Hamas.
