Mr. Biden worked Mr. Obama during their weekly private lunches, imploring him to increase lethal aid, backing a push to ship FGM-148 Javelin anti-tank missiles to Kiev. The president flatly rejected the idea and dispatched him to the region as an emissary, cautioning him “about not overpromising to the Ukrainian government,” Mr. Biden would later write in a memoir.
So, Mr. Biden threw himself into what seemed like standard-issue vice-presidential stuff: prodding Ukraine’s leaders to tackle the rampant corruption that made their country a risky bet for international lenders — and pushing reform of Ukraine’s cronyism-ridden energy industry.
