...when one is weak and poor and stupid   then NO ONE is your friend-only predatory enemies-Riussia include(Boxer-8 nations anti-China expedition).The Japs are a special case-a culture directly offshoot from China-language(esp written/vocabulary-if you speak Cantonese many many words are directly intelligible/recognizeable from Tang dynasty era Cantonese to Japanese).culture food social customs etc.As for America China has proven to be a great peer competitor in all spheres not just military like USSR and as for the Japs if you recall every 300 years or so as the end of dynasties happen with its corruption and chaos the the Japs will raid again-600 AD.1500.and later 1900 as they will bow and scrape and keep their poisonous ambitions hidden until China is dynastically weak again BUT not now as a modern nation state with a good transition of power WITHOUT chaos will keep the Japs quiet as they weaken.A Jap politician blabbing off his mouth is no threat and very hopefully as Taiwan is reunited -peacefully -their stupid jealousy and hatred will get them nowhere-a fight no way with China's every burgeoning power and strength a new Sino-Jap war will only see Japan destroyed.Countries have long historical memorie like Russia disemboweling the Japs in 1945 for vengeance for 1905 Russo-Jap war.
