>The Budapest Memorandum consists of a series of political assurances whereby the signatory states commit to “respect the independence and sovereignty and the existing borders of Ukraine”. But the meaning of the security assurances was deliberately left ambiguous. According to a former US diplomat who participated in the talks, Steven Pifer, it was understood that if there was a violation, there would be a response incumbent on the US and the UK. And while that response was not explicitly defined, Pifer notes that: “there is an obligation on the United States that flows from the Budapest Memorandum to provide assistance to Ukraine, and […] that would include lethal military assistance”.
