Does Israel Seek Deterrence Or War

As a Zionist who knows that the world was 100% correct in 1947 when the United Nations voted to create the State of Israel, and a small d democrat who knows the world and Iranian citizens would be better off if Iran’s ruling Islamic theocracy was replaced by a ruling secular democracy, I have a Zionist fear that Israel’s attempt to restore a deterrence which protects Israel will create a war which will harm the State of Israel.
