Do we really have to do this?
You have to wonder why the US specifically feels it must confront China right at this moment
US to challenge China within hours
Is it that with Russia on the ascendency in the ME Obama feels he must be seen to act giving support to the democratic presidential campaign.
The problem is the boat has sailed. China was permitted to create it's bases in the South China sea in recent times, without confrontation, now a gun boat hardly seems sufficient and all the US can really do is ensure the safe passage of shipping. The US has no territory at risk in the South China sea and can therfore be rightly seen by China as an interloper in territories where they may have a dispute with other nations. This sort of politics place a lot at risk
