It is all very well to complain about 'Chinese aggression' and throw around Nazi analogies, but the sad truth is that everybody is hooked on Chinese production, so China can and certainly will push its claims much further than it has to date.
The US is running a $30B/month trade deficit with China, that allows China to pay for lots of militia boats and a surging Navy. Their $400B deal with Iran and their ongoing port development in Pakistan and the African coast signal their future goals, to dominate the ocean lanes from the Mid East to China. The South China Sea is sort of their equivalent of what the Gulf of Mexico is for the US, Chinese waters beyond discussion from their perspective.
