After 1948, two major motifs were the Holocaust and the Arab-Israeli conflict. Moshe Shamir's "He Walked in the Fields" in 1949 was the first produced by a "sabra" writing about "sabras" in idiomatic and contemporary Hebrew. In the 1950s, dramatists portrayed the gap between pre-state dreams and disillusionment. Other plays pitted native Israelis against Holocaust survivors. Beginning in the 1960s, Hanoch Levin wrote 56 plays and political satires. During the 1970s, Israeli theatre became more critical, contrasting extreme images of Israeli identity, such as the muscleman and the spiritual Jew. In the 1980s, Yehoshua Sobol explored Israeli-Jewish identity issues. Today, Israeli theatre is extremely diverse in content and style, and half of all plays are local productions.
