The release of a video on Saturday showing a message that Haruna Yukawa, one of the Japanese hostages captured by Islamic State (IS) militants, had been slaughtered, shocked both Japanese society and its Western allies. Official institutions in both Japan and the US consider the video is likely to be authentic.

The IS claimed last Tuesday it had abducted two Japanese and gave the Japanese government 72 hours to pay $200 million in ransom for the captives. The Abe administration was put in a conundrum. In front of requests from the victims' families to save the hostages, the Japanese government vowed it would never give in to terrorism on one hand, on the other, it displayed a high-profile stance of striving to free the hostages. But it's believed that the Abe administration would be unlikely to carry out a dramatic rescue, which has already decided the fate of the hostages.

The brutality of the IS has become well-known. They kill hostages in a cold-blooded manner. Now that Japan has become a victim of global terrorism, Tokyo may reassess the challenges it faces. In the past few years, Japanese rightists portrayed China as Japan's major threat, despite the fact that China has never infringed upon Japan over the past century. It's instead  Japan that invaded China and persecuted Chinese people again and again. 

The death of the hostage also offers a new excuse for Abe to lift the ban on collective self-defense. Abe will face fewer hurdles now if he decides to cooperate with the US strategic deployment and strengthen Japan's military activities in the Middle East and its security deployment in East Asia.

Some claimed that Abe is more concerned about promoting rightist policies than rescuing hostages. For the good of peace in East Asia and the Japanese public, we hope such analysis is just speculative. Japan is not capable of playing an active role in the Middle East. East Asian countries are not supposed to be key targets of the atrocious IS. The Japanese hostage case sends a warning signal.

In the aftermath of the 9/11 attacks, the US has spent great efforts in ensuring its domestic security. However, US allies such as European countries and Japan have been constantly targeted by terrorism. It's worthwhile studying the underlying reasons.

The attack on Charlie Hebdo seemingly unveiled the conflicts between the whole of European society and the Muslim community, but it was striking to see how the US tries to remain neutral over the issue.

Having a geopolitical advantage, Japan should be a country without enemies. However, the country is plagued with a terrible mess in its national strategy. It misperceives China as an imaginary enemy. Tokyo's ultimate goal is said to be getting rid of US control, however, it is forced to defer to the US due to its confrontation with China. The killing of the Japanese hostage is more or less the price that Japan has paid for its support to Washington.

We strongly condemn the brutal killing by the IS. In the meantime, we hope Japanese public opinion will take a clear-cut attitude against any terrorist attack launched on China.
