Reinvestigation of the West's Sanctions against Russia in the Crisis of Ukraine and Russia's Reaction

Sanctions are such measures that are used before resorting to force and war. Sanction has been used repeatedly throughout the history. But the frequency of the use of sanction, as a tool to change the behavior of a regime or even a regime change, significantly increased after World War. But the most widespread and newest use of sanctions is between the West and Russia in Ukraine's crisis. In this crisis, America and European Union are trying to change Russia's behavior by imposing large volume of commercial and financial embargo and sanctions against individuals. On the other hand, Russia tries to deal with Western sanctions by imposing sanctions on Europe's citrus as well as European officials. In general, there is an obstacle, called the right of veto, for consensus on the sanctions against Russia and on the other hand, the other multilateral and unilateral sanctions outside the mechanism of the Charter is not contraindicated, but they cannot be imposed unlimitedly and regardless of imperative laws, the general principles of law, the specific rules of the Charter, human rights and humanitarian law. However, in this crisis, the political umbrella has made it actually difficult to apply definitive legal opinion.
