Compared with classical cytotoxic T lymphocytes , NK cells are superior in the following aspects: NK cells are among the first cell types to be activated after intracellular pathogen stimuli, the activity of NK cells peaked between 1 to 3 days, retained during the first 7-10 days, and the T cells response emerged only after 7 days when the NK cell responses begin to decline; though comprising of only 10％-15％ of peripheral lymphocytes, NK cells mobilize most of the cell populations in a strong and high level response to different invasions, and act as key factors at early defense before a specific immune response could mount, while only certain clones were involved in T cell response; NK cells kill virus-infected or malignant transformed cells without pre-sensitization and without restriction by major histocompatibility antigen, which is usually a mechanism of immune escape to T cell recognition by virus-infected or tumor cells, thus NK cell in complementary with T cells play crucial roles in tumor and virus eradication.

Due to the Anpo mechanism, there emerges a contradiction between the Article 9 of its constitution and the new security treaty, giving rise to an internal dispute on the unconstitutionality and the concern over the validity of the Self Defense Forces and causing an argument over the priority of the constitution and the Anpo Treaty. Although Japan is planning to resort to constitutional amendments to solve the problem, due to lack of internal consensus, it remains a long way to go before the controversy could be finally removed.What needs Taiwan's close attention is that how to respond if Japan successfully solves the contradiction of the Article 9, improves its military buildup and change its measures towards the territorial and sovereignty dispute.
