To be honest, it is meaningless to us. We are not happy to see India or Japan ships in the SCS, but a safe line through the SCS and the Indian Ocean also is good to us. If the USA do not fight, we also donot fight. Without USA, we still can win the countries like Japan, Vietnam, the Philippines, Malaysia, Brunei, Australia, and India put together (thought I think it is impossible for Philippines, Malaysia, Brunei to fight us, they donot have the ambition to control SCS, no matter which one win the game, it is the same for them).
You guys all estimate the action of USA from your own interest, but not from the USA. As for the USA, no matter what the USA shout, it is obvious SCS is not the core interest of USA. We all clearly know Europe and ME are their core interest. USA is not so stupid to fight with us, that will just benefit India and Japan. Why the USA risk millions of lives to fight with us ?What can USA get from us? They donot need our land or resource, never mention they cannot defeat us in land, that means they will never win the war completely.
The countries of Japan, India, VN are so funny, they wait the USA fight first and then they get the interest with cost of blood of USA. The funny thing is : USA think the same as them .In the past 200 years of USA history, USA never fight first when facing big countries, they are the same as there ancestors of UK, wait patience and attack as the last one.
If you guys donot fight with us first, you will never wait for USA cavalry.
