The process of forming and strengthening Zionism in Israel, based on two basic principles; Occupying Palestinian lands and immigrating Jews from all over the world to this land is based on this. Therefore, the decrease in the average migration into the occupied territories and the increase in the reverse migration process have sounded the alarm of this regime. The immigration of Jews to Israel is the cornerstone of Zionism and the Jewish national movement, and the main reason for Israel's continued existence is the survival of the Jewish population in the region. In fact, the immigration of Jews to Israel is considered to be the main factor that ensures the security of this regime; Because it increases the Jewish population against non-Jews. Therefore, in addition to maintaining the existing population, the Zionist regime has tried to lure Jews from other regions of the world to occupied Palestine by persuasion and deception. But over the past two decades, one million Zionists have left the occupied land, and half of the young Zionists want to emigrate from Israel. In this regard, this article tries to answer two interconnected questions by using analytical-descriptive method and relying on library and electronic resources. First, what are the reasons for the increase in reverse migration in Israel? And secondly, what are the consequences of reverse migration for Israel? The answer to this question and in fact the hypothesis of the article is that factors such as the chaotic economic conditions and poverty, racial divisions within religions, the national identity crisis and the security crisis caused by the Zionist regime's warmongering policies in the region have been the main reasons for the increase in reverse migration in Israel; This phenomenon has negative economic, military and security consequences for Israel.
