Japan and Biden tackle nuclear threats at G7 summit in Hiroshima.

Japan is hosting the G-7 summit in Hiroshima with the goal of advancing Prime Minister Fumio Kishida’s dream of “a world without nuclear weapons.” However, the world is moving rapidly in the opposite direction, putting a spotlight on President Biden as he faces pressure to simultaneously stand up to nuclear-armed adversaries and advance the cause of disarmament. With the world’s largest nuclear powers clashing over the war in Ukraine and the threat of proliferation increasing in China, North Korea, Iran and elsewhere, the summit in Hiroshima presents a stark reminder of the growing threat under his watch as well as a challenge to prove that the United States can still lead the global community away from the brink.
