Just think about NATO and many Americans defend NATO without a hesitation. The problems are that there are so many unknown dangerous factors in so NATO members. A blank check to defend them should not be correct.
Recently Japan picked up a new female defense minister Ms. Inada. See http://www.usatoday.com/story/news/world/2016/08/15/japans-new-outspoken-defense-chief-courts-controversy/88753106/. She also denied the World War II atrocity in China. There was a Contest to Kill more Chinese Using a Sword between two Japanese officers. The winner killed 106 Chinese and the loser killed 105 as shown in the Japanese paper. The story was widely published in Japan newspaper to encourage men to join the Japan Imperial Army.
A history replay:
The Japanese newspaper during World War II reported a competition between two generals in China “Who can kill 100 Chinese and hang their heads first?” as following:
In 1937, the Osaka Mainichi Shimbun and its sister newspaper the Tokyo Nichi Nichi Shimbun covered a contest between two Japanese officers, Toshiaki Mukai (向井敏明?) and Tsuyoshi Noda (野田毅?), in which the two men were described as vying with one another to be the first to kill 100 people with a sword. The competition supposedly took place en route to Nanking, directly prior to the infamous Nanking Massacre, and was covered in four articles, from November 30 to December 13, 1937, the two last being translated in the Japan Advertiser.

We should ask ourselves :
- If this new Japanese defense minister accidentally/secretly attacks China to promote her agenda and China fights back, should US come to defend Japan?
- People should not forget Japan attacked US during World War II even US gave an almost free pass for Japan attacking and evading China for quite a long time.
- If German chose a World War II atrocity denier as a defense minister, what will happen to the German government?
There are more and broader benefits for a good US-China friendship. When the US-China relationship is stable, there will be nothing serious happening in the Pacific. However, when some US politicians or newspapers give a false hope to some Asian countries, they will be bold to attack, just like WWII.
