The US election was 8 months ago. The operation was probably still in the planning stages. After that day, Ukraine would have known not to share any sensitive info with the US unless absolutely necessary, knowing that a Putin fanboy would soon have his hands on it. Had Biden still been in office today, he may have gotten a heads up before the actual execution, but then again, why would he need it. It is not like that information would have been actionable to anyone except the target.
Was it because Trump didn’t say “thank you” after the last time Ukraine shared top secret war plans?
