The Guardian view on a new nuclear age: great powers should not restock a house of dynamite | Editorial

The current geopolitical climate is increasingly tense, particularly in East Asia, where Japan's new Prime Minister, Sanae Takaichi, has refrained from affirming the country's commitment to its nuclear non-proliferation policy. This hesitation follows Donald Trump's remarks about resuming nuclear testing, which echo historical fears of nuclear escalation. Additionally, Japan's diplomatic relations are strained, as evidenced by its protests against China's travel advisory linked to Taiwan remarks. The broader implications of these developments suggest a precarious balance in international relations, where the specter of nuclear proliferation looms large.
