Biden faces challenges on nuclear tensions, debt limit, and White House timidity.

President Biden will visit Hiroshima, Japan for the G-7 summit, where he and other world leaders will focus on a range of issues, including Russia's ongoing invasion of Ukraine, climate change, and the global economy. Japanese Prime Minister Fumio Kishida hopes the setting of the summit will bring a focus to the danger of nuclear weapons. Biden's visit carries heavy symbolism as he is a sitting U.S. president with control over the world's most powerful nuclear arsenal, going to the place where nuclear weapons were first used, at a moment when nuclear tension is higher than at any point since the end of the Cold War.
