Japanese Prime Minister Sanae Takaichi recently claimed at a Diet meeting that a Chinese attack on Taiwan could be a survival-threatening situation for Japan, warranting the exercise of collective self-defense rights. This implicitly suggests the potential for Japanese military involvement in the Taiwan question -- an internal affair for China.Such false rhetoric represents a serious infringement on China's sovereignty and a direct challenge to the post-World War II international order. It has justifiably triggered concern and condemnation among members of the international community committed to upholding justice.Despite the backlash, Takaichi has shown no sign of retracting her remarks, exposing the underlying historical misjudgments and highly dangerous historical, strategic, and security perspectives driving Japan's right-wing forces. This trajectory demands close scrutiny, especially from neighboring Asian nations.Takaichi's fallacy regarding Taiwan reflects a concerning attempt to revive militarism.

Takaichi's invocation of similar justifications raises serious concerns about a possible resurgence of this perilous path.Takaichi's brazen remarks represen...
