The Torah commands specific ancient wars, but the rabbis confined 'commanded war' so tightly — requiring prophet, king, and Sanhedrin — that the category became inoperative; what remained is self-defense: 'if one rises to kill you, rise first.' How Jewish law should govern a modern army, and whether Zionism is a religious duty, a secular project, or a mistake, are live disputes across the Orthodox, Reform, and Haredi worlds.

REVIEW — SOURCES DIVIDED
Zionism's relation to Judaism is genuinely contested: religious Zionists give the state religious meaning, many Haredi authorities historically denied it any, and secular Zionists framed it as national rather than religious. Scholarship reports a spectrum, not one Jewish position.
