Which one among the following statements about ‘Revolution’ is not correct?

In political theory, a revolution is defined as a fundamental socio-political transformation that involves a change of the system itself. It signifies a complete reordering of the established political and social structure, rather than mere modifications. Conversely, 'reform' is the term used for making internal changes or modifications within the existing system's rules without removing it. Therefore, the statement that revolution implies change within the system's rules is incorrect as it describes reform. Historically, revolutions are born when political systems fail to react to changing social climates, and no system is inherently immune to such upheavals [1]. While some modern theorists suggest revolutions can be peaceful, they are typically characterized as sudden, often violent upheavals aimed at upturning the established order [1].
