This interview with Howard Zinn opens with a discussion of a group of Israeli refusers known as the Sministim (high school seniors).  For some years now, a number of high school seniors get together and write a letter in which they declare their refusal to serve in an occupying army.  Some are pacifists who won’t serve in any army, and others object specifically to Israel’s 42 years of occupation of Palestinian Territories. Some of these refusers (and well as many reserve soldiers who have become refusers) have served jail sentences.  International law requires recognition of the right of people to refuse military service, but this – like many other laws and conventions – have been ignored by Israeli authorities.
