In order to evaluate one's actions whether they are moral or not, we use many moral dilemmas. One of them is Kant's categorical imperative. This essay presents Kant's project of categorical imperative. Then, I will explain that rulers should appeal to Kant's categorical imperative when making foreign policy decision.

Thus, in order to provide this stability which means that continue to stay among other states, states should act through the principles of categorical imperative which are universally valid, good intention and never using people or other states as means to end. The second reason is that if rulers appeal to categorical imperative when making foreign policy decisions, the world can be more peaceful. Since, wars and conflicts which are caused by bad intention, using other people or states as means for gaining advantages which are not universally valid can be hindered by categorical imperatives. Finally, I will conclude that the Kant's categorical imperatives are still valid and necessary when rulers are making foreign policy decisions.

These are universal law, ends as a means and the importance of intention in conducting of human behaviour. Firstly, according to Kant, one's action should be universally valid. Universal validity means that people should think behaviours and they need to judge their own behav ...
