First and foremost, in my own point of view the prioritization of Realpolitik over balance of power or isolationism often result to pursuing national interests without pondering the moral or ethical principles and which might potentially led to actions that harm other states or individuals.

Furthermore, another crucial aspect of prioritizing the concept of Realpolitik over balance of power or isolationism is, it causes in injustice. In other words, the concept might tend to pay a deft ear to the principle of balance of power or isolationism which might result to unjust distributions of power or resources and result in magnifying disparities and unjust on a global scale.

To sum up, the other significant factor of prioritizing realpolitik over balance of power or isolationism is that the concept of Realpolitik might frequently result to actions that will compromise international laws and norms, eroding the starting point of the rules-based international order.
