A number of nuclear tests conducted by North Korea has changed from 3 to 6 during the past two years. There also have been more missile tests carried out in 2017 than ever before in the history of North Korea[1]. Therefore, it is not surprising that international community started to worry about the security and stability of the current status quo. As the situation is getting worse, some of the international actors – including superpowers like the United States – start to consider a more emphatic approach, without excluding a military pre-emptive action. In my opinion it is not the wisest idea. The world history reveals that pre-emptive action against autocratic regime could bring dangerous instability – not to mention about possession of a nuclear weapon. That is the reason why I am convinced that it would only make things worse and escalate tensions between North Korea, its neighbors and the rest of the world. I believe that word leaders should consider diplomacy as the most effective tool to solve the current issue. Coordinated recall of diplomatic representatives, as well as other types of punishment, i.e. more effective arms embargoes or stronger economic sanctions – also could be considered.
