The international "delegitimization" of Israel is an invention of hardline Israelis. There is no international movement questioning Israel's legitimacy, there is however one that questions the legitimacy of the occupation and the settlements. Israeli right-wing politicians capitalize on this by confusing the issues and present the rest of the world as an external threat to Israel. That's a classical way to create national unity and support for the policy of the government. It is sad that it works so well even in an open democracy like Israel.
