The knesset member who suggested nuking gaza is truly one of the dumbest nutcases israel has to offer. Not only will such an act be terribly cruel, it would also hurt places like tel aviv, which is just 50 KMs from the strip, and harm millions of Jewish Israelis (who are presumably the nationality he seeks to strengthen)
