Didn’t Russia just recently sink a Chinese ship that was in its territorial waters? I hardly would call this a test for Obama. Its comparable to giving the moon to your enemy. I though George W reacted poorly when the Chinese forced that recon plane to land early in his presidency and then stripped it of its electronic equipment. But you got to wonder what it will take for Obama to react to provocation.
The Russians are of a completely different mind set. They lost 20 million people to Hitler and the Nazis. The idea of "Protect the Rodina" is deeply ingrained in their actions.
If one so much as scraped the paint on an American warship or military vehicle, it was at one time considered to be Causus Beli. We should have lanuched an F/A-18 strike on that aircraft to make the point to all observers. In my view, it would have put off potential trouble in that region for a long time.
If some PLA Military intelligence people got hurt or killed in that strike, well...cost of doing that kind of business.
