The unnamed official is said to have made several comments that exposed a basic lack of knowledge about the war between Ukraine and Russia during trilateral peace talks in Abu Dhabi last week. Ukraine does not have a vice president and Budanov has recently been appointed as head of the President’s office. “I think it's the longest war now,” the US official is reported to have said erroneously during the meeting. The Ukrainian leader warned the escalations were a signal that Russia is preparing a “new massive strike” and said the onslaughts discredited peace talks.
