The main purpose of this legislation is to strengthen the United States' stance against Russian influence and aggression in Ukraine. It aims to ensure that the U.S. does not recognize any claims made by Russia over Ukrainian territory that it occupies, particularly regions like Crimea and parts of Donetsk, Kherson, Luhansk, and Zaporizhzhia. Key provisions of the legislation include a clear policy statement that the U.S. will not acknowledge Russian sovereignty over occupied Ukrainian territories.
