The SCS will not amount to much, imo. See that USN vessel... it could kill about 30 of those Chinese WWII vintage destroyers in about 30 seconds...sorry... two minutes...and China knows this... they won't mess with us.
What's good about this, is we will be watching. And they don't even know how close we will be watching. My son knows about this stuff... we are watching and studying, and positioning forces 24/7... and China knows we are watching, they just don't know what we know. China needs to give it up... join the Western Economy once and for all, and take care of that asshole in N. Korea.
