Japan should not intervene in other countries' conflicts by using military power. And I don't think Japan is capable of doing such things. For starters, I don't believe our country has sufficient human resources to make that type of international contribution.

Japan's diplomatic efforts could have had a broader international perspective. Relations with the U.S. are, of course, the cornerstone of Japan's diplomacy, but the U.S. acts on its global strategy. For instance, Washington suddenly got closer to China in the early 1970s as part of its strategy against the Soviet Union.

Japan needs to cooperate with China economically. This is understood better by the business community than the government.
