It pains me to say this, but Israel should close its army radio station. Just not now.Israel's defense minister, master politician Israel Katz, wants to shutter the station known as “Galatz,” its Hebrew acronym, because some of its broadcasters are critical of his government.In contrast, the only legitimate reason to shut down the 75-year-old institution is this: It is improper in a democracy to operate an army radio station that broadcasts to the general public.Why does it pain me to say that?
