Whatever the PLA-N might have inc. their Carrier Group & Stealth Aircraft etc., if any of these are used in the Scarborough Reef Conflict against the Philippines, it clearly shows to countries in South & East Asia that China will use ALL its might to crush anyone that does not "kowtow" to its demands & rights. Now most of us will realise why we need the US to stop aggression by any BIG power against a very small countries like the Phillipines, Vietnam & the other claimants in the South China Sea. Cooperation & good relations among Asian countries could be just fallacy. There is still time for China to be diplomatic & settle the South China Sea Territorial disputes at the International Court of Justice. Get respect & not try to impose on its will by FEAR. Imperial Japan tried to do it in Asia in WW II but FAILED miserably with disastrous consequences.
Pl look at the map of S.E. Asia and the South China Sea, there is sense to be made re: territorial boundaries. How far is Scarborough Reef from Philippines compared to Hainan Island (China)? However, let common sense prevail & settle it under UNCLOS - and final decision at the (UN) International Court of Justice (Hague). I believe this is FAIR - & accept the court's decision. Don't base on "Ancient History". If Ancient History is to be used, then Italy can claim many of its Ancient territories because of the Roman Empire. Also the Ottoman Empire (Turkey), Persian Empire (Iran), British Empire (UK) etc. etc. There will be no end but arguments based on Ancient History. So let's be factual & realistic - Go to International Court and be FAIR. The decision will be accepted by all parties & there's TRANSPARENCY.
