CEVAP:

Beginning in 1970s, the liberal theory evolved into a more realist version compared with both classical liberalism and liberal internationalism. This became more apparent with the welfare liberals who based their ideas on Keynesian doctrines of increased role of state in economics that brought economic nationalism on the agenda again. The doctrinal elements of liberalism were reevaluated under the light of changing international circumstances (MacMillan, 2007, 26). In the decade after 1970, international organizations still mattered and were accepted as independent variables creating influence on states. With it, there was a new “institutionalist” turn in the liberal theory, still shaped by the Grotian tradition since the emphasis was on rules voluntarily established by states for order in international relations (Viotti & Kauppi, 2012, 145). The post-WWII development of the liberal tradition in IR theory was a departure from classical liberalism towards regional integration namely neofunctionalism, followed by institutionalism (Nye, 1988, 241).
