She's 15 and has already been through four wars: 2006, 2008-09, 2012, 2014. She's qualified to make comparisons — this war worse than that one, the latest one worst of all.

Her interlocutor is Akihiro Seita, a Japanese doctor working there with the United Nations Relief and Works Agency. Seita wrote a book, which Shukan Josei magazine discusses, called "Gaza: Senso Shika Shiranai Kodomotachi" ("Gaza: Children Who Know Nothing But War"). The contrast with Japan could not be starker. The only Japanese who can claim the knowledge every Gaza child takes in with his or her mother's milk are those over 70.
