The president of the United States has visited Kyiv ahead of the first anniversary of the Russian invasion of Ukraine. We ask about the drama and the logistics of a visit kept secret until Joe Biden was on the ground, a visit punctuated by air raid sirens. How times have changed since a year ago, when Biden was derided on the world stage over the messy US pullout from Afghanistan. What standing does the US have today?
We ask about the war effort, Biden's pledges of support in Kyiv and those of EU foreign ministers meeting in Brussels as both Ukrainians and Russians gear up for spring offensives.
The US president is not the only one on the move. After his weekend meeting with Biden's secretary of state in Munich, China's top diplomat is expected in Moscow as Washington accuses Beijing of considering weapons for Putin. What's the score in this superpower standoff over Ukraine?
