USA will not meddle in the South China Sea territorial dispute on behalf of tiny Vietnam or Phillipines, but they will make alot of sweet talks to enhance her diplomatic and military clout while spoiling the relationship between the neighbouring countries, it's all about gaining political and economic influence at the expense of these territorial disputes. In the end Phillipines and VIetnam will lose, USA will gain, and they will still never directly confront China, because they know the consequences, they want to gain a bigger economic and military foothold in these countries and continue to create animosity so they can grab a bigger share of the future Asian economic pie. Naturally Vietnam will have no hope of ever competing with China over island claims that are not within Vietnam's own territorial waters, Vietnam absurd claim is the weakest among all nations and they have no historical ties to these islands, so in the end Vietnam will get nothing, a country that is economically dependent on China, trying to roar like a tiger has really been turning down their volume in the recent weeks and waking up to reality, not to rely on an unreliable third party who cannot save them, now it is Philippines who's making all the noise wanting to get third parties involve, it is no problem, China have all the time in the world to wait it out, USA will not declare support for the Philippines over these territorial disputes, they may be a blow-hard and big mouthed, but they also know where the red line is. Philippines is always a pawn, Vietnam is a willing pawn, over-ambitious and not knowing her limitations and reality.
