The book 'War' by Robert U. Woodward reveals President Joe Biden's mistakes and misjudgments in dealing with Russian President Vladimir Putin and the conflicts in Ukraine and Israel. The book highlights Biden's foul-mouthed criticism of Barack Obama's response to Putin's seizure of Crimea, as well as his disastrous decision to withdraw US forces from Afghanistan. Woodward also discusses Biden's reluctance to support Ukraine and his preoccupation with his son Hunter's personal struggles. The book ends with contrasting views on former President Donald Trump's leadership.
