WARSAW – In Paris, West Berlin, London, and Rome, the spring of 1968 was marked by student protests against the Vietnam War. In Warsaw, too, students were protesting, but their cause was not the same as their Western counterparts. Young Poles took to the streets of Warsaw not to chant “Ho, Ho, Ho Chi Minh” in solidarity with the Viet Cong, but rather to defend their own country’s freedom and culture against a smothering Communist rule.
