If you're like us, you've not taken your Birthright Israel tour. But you know who did The cartoonist Sarah Glidden. And you know what else she did? She chronicled it in her 2007 memoir “How To Understand Israel in 60 Days.” Glidden is Jewish and progressive, living in New York City, when she departs on her tour. She goes in with some preconceived notions and by the end she’s far less definitive in her point of view. Using rich water colors, Glidden details the day-to-day aspects of her tour where she learns about Israel’s history, but also can’t help questioning what she’s learning, or the way in which that history is communicated. This may just be the episode that gets us cancelled.
