The United States and other world powers have declared That Russia`s action in Ukraine is a clear violation of its international agreements. One of these agreements is known as the Budapest Memorandum, signed in 1994. After months of political turmoil and the abrupt departure of Ukrainian President Yanukovych, Russian troops invaded Ukraine`s Crimea peninsula in March 2014. On 18 March, Russia announced the annexation of Crimea due to protests by the Kiev government, the UN Security Council and Western governments. The United States, the United Kingdom and Ukraine have characterized this action as a flagrant violation of the security guarantees of the 1994 Budapest Memorandum. However, according to the Russian Foreign Ministry, security guarantees were given to the legitimate government of Ukraine, but not to the forces that came to power after the coup.” The United States, Britain and Russia welcomed the Kiev regime`s decision to accede to the non-proliferation agreement, including a commitment to respect Ukraine`s independence and “existing borders.” In 1994, Ukraine signed an agreement with the United States, the United Kingdom and Russia, under which it gave up its nuclear arsenal in exchange for certain assurances. NPR`s Arun Rath discusses the agreement with Steven Pifer, former U.S. Ambassador to Ukraine. Russia denied violating the Budapest memorandum on the grounds that the Ukrainian government had changed. In March 2014, Russian President Vladimir Putin said that the departure of Ukrainian President Viktor Yanukovych in an “unconstitutional coup” – or “revolution” – had led to the creation in Ukraine of a “new state with which we have not signed binding agreements.” German journalist and Ukraine expert Winfried Schneider-Deters agrees with the DW: “The agreement is not worth the paper on which it was written.” And the 1994 Budapest Security Insurance Protocol was the document that reflects these U.S. commitments. Russia has also joined Britain in giving assurances to Ukraine, including respect for its territorial integrity.
