re: putting israel air strikes into perspective

I'd imagine the Israelis have been flying two different types of airstrikes. Operational airstrikes that target the sites from which Hamas has been launching rockets into Israel, and airstrikes that target individual Hamas members. The Israelis have been gathering intelligence on Hamas and its members for years. They know who the members of Hamas are, and they know where they live. They probably have an extensive list of targets that they are working their way through.
