How does Lawrence O'Donnell compare Donald Trump's approach to Russia/Ukraine with historical US wartime leadership?

O'Donnell draws a stark contrast between World War II alliances and Trump's approach to Russia-Ukraine. He highlights how Roosevelt and Churchill maintained unified fronts with Stalin despite mistrust, repeatedly promising not to engage in separate peace negotiations with Hitler. This alliance solidarity was crucial to victory. Conversely, Trump broke with US allies by sending a delegation led by Secretary Rubio to negotiate separately with Putin's representatives regarding Ukraine. This undermines the international coalition supporting Ukraine's sovereignty, echoing historical concerns about separate peace agreements that could have changed the outcome of WWII.
