["World domestic policy" as a way to eternal peace? Carl Friedrich von Weizsäcker's realistic idealism as theory of a sustainable policy].

The intention of this article is to show the suitability of "Weltinnenpolitik" (world domestic policy) as an analytic and programmatic view on contemporary policy. A full reconstruction or comparison of Carl Friedrich von Weizsäcker's concept is not at the focus. As mentioned in other contributions to this volume, Weizsäcker did not refer to the disciplinary discourses in detail. His approach is particularly 'unique' since he set about in 1963 to study the conditions of peace in a very general way. By doing so, he was able to circumscribe the conditions of peace realistically: those valid for us today and apparently also in the future. Weizsäcker probably did underestimate the complexity of the transformation to sustainable politics for preventing climate change. Vice versa one should hope that we today do not discount the prevention of atomic war as a sine qua non for sustainable climate-saving policy. Both could mark the quintessential conditions for peace.
