A main impetus for Russia's invasion was a desire to prevent Ukraine from joining NATO; it's unclear whether another collective security agreement would be any more palatable to Moscow. Some US officials were surprised by the declaration from Ukraine after the Istanbul talks that Western security guarantees could be on the table. "But there is nothing specific about security guarantees that I can speak to at this time." The theory that Russia would not attack Ukraine if it had Western security guarantees appears to still be a bigger risk than the US and its allies are willing to take. Anastastia Radina, another member of Ukraine's parliament, said that Ukraine is looking for "workable security guarantees and not just another Budapest Memorandum."
