How US warships conduct FON-related transit will be a big deal. I say that because senior USN officers recently made several comments about showing FON by sailing anywhere international laws allow. So, the way I see it, it's lose-lose no matter what happens now, because if Obama orders his admirals to stay out of 12-mile limit, then US loses credibility. Alternatively, if Obama orders his admirals to sail to within 500m of artificial islands, and PLAN shadow US ships with a strong force, then the region think US still stronger, but China is serious about challenging US military primacy. US might still lose some credibility, but not as much as talk loudly and carry no stick. Finally, China might use US show of force as cover to militarize some of their new artificial islands, thereby increasing regional tension.I am sure all the conceivable scenarios that we discussed and more are being considered, played out and contingently prepared. I think the US actions and what they would do as part of the transit is more predictable. I do not know how to read Chinese probable actions and is more of an unknown to me.
A transit passage by nature is benign. A lot is dependent on the Chinese side on whether to treat it as a non event or not.
All of the above are lose-lose, unless China backs down and accept continued US primacy. And what are the chances of that? My guess is slim to none, and slim already left town.
