The present paper is based on the analysis of the last “acts” of crisis between Belarus and Poland. The questions for discussions are many and open. On the one hand, the conduct of Belarus prohibits general principles and rules of public international law. Protection of migrants, human rights, violation of the external borders of a state and violation of the borders of neighboring states are topics that despite being protected for many years by the rules of international law remain violated by Belarus. On the other hand, the attitude of Poland as a Member State of the European Union and with the way it reacts in this border “crisis” opens up the discussion of international responsibility, the enforcement or not of countermeasures to international crimes and whether it behaves as a democratic state according to the principles and values of the European Union.
