to those that think the US will help us in an event of war, i dont think so unless its a deal that the US gets to own the PH if they win the war. besides, China is the US biggest trading partner right now, if they were to choose between the PH and China the answer would be obvious. when it comes down to economy and thier nations welfare the US wont care about our so called democracy and thats a fact.
and the reason for spratly probably isnt for resources, its more of strategic placements of radars, anti ship missile defence and naval/air ports to extend thier naval/air operations safe zone. like what the US is doing to the PH, Japan and SKor, the "bases" they just bribe governments for it.
