Netanyahu is pandering to the religious right
This is an election campaign, and in an election campaign you have to promise that 'we'll keep Jerusalem' and teach our children about Jewish tradition.
In the previous election campaign Benjamin Netanyahu promised change, but back then he was in the opposition and wanted to return to power. Now, when he's asking the voters for four more years as prime minister, his campaign slogan should be "No change," "I don't want change," or simply "Netanyahu. The status quo."
