Never mind the Hamas officials, they need to take out the voters.
2006 Elections, Hamas won a majority by 44% of the vote, the same proportion as Hitler and the Nazis won in the Reichstag elections of 1933. We didn’t hestitate to carpet bomb German cities in order to win the war that eventually resulted. Israel would be fully justified bombing the absolute crap out of Gaza, taking over what is left and comprehensively de-Hamasising the survivors.
