Sandler contends that the impact of the nation in foreign policy is not synonymous with that of the State. Understanding the effect of the nation is important because of the contemporary reawakening of primordial national aspirations. This study is designed to test these views by examining nation-centered concerns in foreign policy as practiced within Israel. It reviews and analyzes the roots of the territorial dimension in Israeli foreign policy since the establishment of the state up to the present; the impact of Israeli domestic politics; and the rise and fall of ethnonationalism in Israeli foreign policy. As such, the work is of concern to all students of Israeli politics and foreign policy and the Arab-Israeli conflict.
