In his book, Biden called Zelensky capricious, stubborn and not grateful enough. He also told how he prevented the Trump team from starting negotiations with Russia.
"In our private conversations, Zelensky can be moody and stubborn and not as grateful as I expected," Biden writes.
He recalled of Putin that he spoke in an irritated tone, and during meetings he liked to lounge on a chair, feigning indifference, "like a boy."
Biden also said that after Trump won the 2024 election, representatives of his team asked to sign a letter that would allow them to begin direct negotiations with Putin before the inauguration.
However, Biden refused because he did not want to give them "carte blanche for what I expected to be some kind of capitulation at the expense of Ukraine."
