CEVAP:

In this context, the first great debate is vested in between idealism and realism; the second in traditionalism and behaviourism; and the third in positivism and post-positivism. The debate on idealism and realism primarily focuses on numerous evaluations of the nature and the functioning of international relations; whereas traditionalist and behaviourist debates deliberate
on the clash of different methodologies concerning the scientific aspect of international relations. The positivist and post-positivist debates on the other hand, compromise the differences of opinion forming the basis for various unravelling aspects of IR theories such as the questioning of all their outpresence, validity and efficacy, and the advancement of alternative perspectives.

In addition, debates on IR theories can, at times, be subject to different
classifications such as rationalist vs. reflectivist, traditionalist vs. critical, formative vs. explanatory, foundationalist vs. anti-foundationalist etc.
