EVEN HIS critics admit that Tucker Carlson offered a riveting podcast performance on June 18th when he grilled Senator Ted Cruz about his zeal for bombing Iran. Did Mr Cruz really believe that the Bible’s command to “bless” the nation of Israel required America to join Binyamin Netanyahu’s war? Did Mr Cruz know basic facts such as the population and ethnic make-up of the country whose rulers he wants to overthrow? The Republican senator from Texas shifted uncomfortably, accused Mr Carlson of having an “obsession” with Jews and later dismissed his “gotcha” questions.
