What it's your opinion on this discussion : On a personal level, I would say that realism is the approach that appeals to me as it's the one that is clear to see in our world. Even if most may not admit to it, individuals and states are always trying to ensure their security and safety whilst trying to obtain as much power as possible. We can see on an international level how countries are more often than not trying to gain more power which will serve to the benefit of their state. Given that this approach deems the international system to be anarchic, states must engage in self help.
Power is the most important factor in realism, this acknowledgment of how power shapes peoples and states behavior is a significant strength. Being realistic about a state's intentions on international politics can be shown throughout our history from wars and the many conflicts we have witnessed. However, the idea of power is all can also be the weakness as it can lead to states treating politics between states as a competition and with power being left in the balance.
Although I would like to veer towards a different way of thinking, I believe the current political climate we live in can only be seen from the approach of realism. The constant battle for power between the superpower nations and the difficulty in finding solutions can be seen in many cases.
