December 5, the draft resolution appeared on the official website of the Verkhovna Rada of Ukraine entitled "On appeal of the Verkhovna Rada to the governments, the signatories of the Memorandum on Security Assurances in Connection with Ukraine's Accession to the Treaty on the Non-Proliferation of Nuclear Weapons Memorandum of December 1994, on the steady implementation of safeguards. The explanatory note to the draft states that in case of further breach of conditions, Ukraine assumes the right to reconsider its status as a state without nuclear weapons.
“In the event of subsequent non-compliance by the States-signatories with the conditions stipulated in the Memorandum on Security Assurances in Connection with Ukraine's Accession to the Treaty on the Non-Proliferation of Nuclear Weapons Memorandum of December 5, 1994, Ukraine will have to consider the possibility to resume the status of the state with nuclear weapons,” the document says.
The draft resolution was developed by Ukrainian MP Sergey Kaplin.
In January 2016, Sergei Lavrov, the Foreign Minister of occupying state (according to the UN resolution on human rights in the Crimea) claimed that Russia had not violated any obligations under the Budapest memorandum, because it stipulated only one condition: "not to use nuclear weapons against Ukraine." However, the Minister for Foreign Affairs of Ukraine Pavlo Klimkin urged him to carefully read the Budapest Memorandum, and make sure that "there are not only paragraphs 4 and 5, mentioning nuclear weapons."
