I agree with what you wrote. SCS situations right now is perfect balanced for all side except US. In Vietnam all the news about SCS islands is keeping the ancestors islands ( basically mean all of islands of SCS belongs to Vietnam). But who knows the truth is yeah Vietnam is actually lost some islands to Philippines, China etc but still keeping some islands. This mean you take what you can, base on how powerful are you. I don't think Vietnam can reclaim more islands if don't want to piss all other side. And the Communist Party of Vietnam clearly know this. If US want to fight with China to take China control islands then go ahead, do it yourself Vietnam will gladly watch this fight from far away with some deeply concerned.Exactly, I don't think it's in any countries in the region's interest to stir up SCS. And that includes China.
So all these "news" from the MSM about China's assertion, etc. Is all made up to stir trouble.
The only countries that can benefit from the stir up is USA and OZ. Although I'm not quite sure what OZ get out from this. I think they just still haven't grasp the notion that the world order has moved on, and they need to re-adjust. They really need to see which side their bread is buttered, and the quicker they realise that, the better it is for them and the region!
