Reports indicate that former President Donald Trump has not outright rejected the idea of resuming subterranean nuclear testing. This follows the termination of past treaties stipulating nuclear non-proliferation and a fall in US international standing on the issue. However, no official decisions have been made, and there are ongoing calls from various quarters for renewed efforts toward nuclear deescalation.

For Japan, being the only country to have experienced nuclear bombings, this news reopens old anxieties about nuclear warfare. Japan has consistently been a staunch advocate for nuclear non-proliferation, and any potential threats to these principles are scrutinized intensively in the media and among public discussions.

In contrast, the US and EU have diverse sentiments on these issues. While some citizens and policy makers echo Japan's strict anti-nuclear stance, others are less definitive, reflecting a broad spectrum of geopolitical interests and ideals. Nonetheless, any return to nuclear testing would likely ignite heated debates in these regions.
