The end rather than the means
Japan needs to recognize that its strategy toward China should be in pursuit of lasting friendship not just benefits
In order to realize the goal of becoming a "normal" state, Japanese Prime Minister Shinzo Abe has adopted the strategy of trying to revise Japan's peaceful Constitution and break up the post-war order, build up its alliance with the United States, and play up the "threat" from China to support its military buildup.
This strategy, along with the denials of Japan's military past, have aroused opposition from domestic political parties as well as neighboring countries such as China and the Republic of Korea. It will almost certainly lead to contradiction with the US as well, because it seeks stronger military forces and more independence in the alliance between the two countries, and relies heavily on an assumed strategic confrontation between China and US, underestimating the growing cooperation between them.
