The future standing of the law in world politics can only be predicted in variants. Four scenarios for the future of the world political system appear to be the most
probable: 1. the strengthening of the hegemony of the USA; 2. chaos; 3. effective multilateralism; 4. parallel worlds. At the beginning of the 21st century, efforts to consolidate the hegemony of the USA without regard for the real power of the given state led to a deepening of chaos – i.e., the proliferation of nuclear weapons, destruction, a growth in international crime, the spread of terrorism, the beginning of the global financial crisis and soon. The strengthening of the role of international law and the improvement thereof is only possible given the establishment of scenario no. 3, i.e., during the cooperation and mutual trust of the world powers. Some information about economic, demographic, but also the politico-military development indicates that the world is approaching the establishment of scenario no. 4, where different, relatively closed power centres with varying concepts of globalisation will exist next to one another. The specific weight of the West would fall further in this world. For small states such as the Czech Republic and Slovakia, which are dependent upon treaties with allies for their security, it is unconditionally necessary for these treaties to be adhered to in good faith. Therefore, scenario no. 3 is the only hopeful scenario for their future. Only given the establishment of this scenario is it possible to create the world without nuclear weapons, which US President Barack Obama spoke of in his speech in Prague in April 2009.
