US WITHDRAWAL FROM THE OPEN SKIES TREATY: CONSEQUENCES FOR INTERNATIONAL SECURITY AND STABILITY

The arms control regime consists of several documents, and the United States of America and the Russian Federation as the State-Parties ensured the implementation and effectiveness of them mostly. However, the growing conflict between these States due to Russia's numerous violations of international law and obligations under international agreements has also harmed arms control. The withdrawal of both states from strategically important documents, which were tools for maintaining transparency and mutual control, is a result of the decline in trust and the lack of a constructive dialogue between Washington and Moscow. The Open Skies Treaty is one of these documents. The article examines the United States' reasons for the withdrawal from the Treaty and reveals the consequences of such a decision by the administration of President Trump. It is noted that the agreement, the idea of ​​which belonged to the United States, was signed immediately after the end of the Cold War and was to help build trust and openness in the new environment. It is noted that the Treaty ensures international stability through the ability of each party to openly collect information on the armed forces, activities, and operations of another party through coordinated flights of reconnaissance aircraft over the territory of the member states. However, problems are gradually accumulating due to Russia's actions to restrict flight zones in violation of the provisions of the Open Sky Treaty, which has become especially acute since 2014. That made the United States think about the meaning of participating in an agreement where one of the parties violates its provisions. The authors outline the consequences of the U.S. decision to leave the agreement; in particular, the focus is on the reactions of the U.S. European partners and Ukraine. They also examined applications and countermeasures by Russia that has also announced its withdrawal from the agreement. Reflecting on the prospects for international security and arms control, the preconditions for the potential return of the United States and Russia to the Open Sky Treaty are outlined.
