My thoughts are
What is it about Germany that really concerns you?
Of late, Germany seems to be angling to head up a Europe unified against the US--and they may not be squeamish about using force to do it.
As for Russia and China, the data confirms a real threat. Also, look at the source of the very first source and deliver to me something that would indicate that Bill Gertz is not a valid source (Washington Times or not)?
My argument is less with the facts than what those facts actually mean.
China has a LOT of catching up to do in order to pose a credible threat to the United States--and they are not building one of the critical components--a modern Navy, with enough combat sealift to land a corps-sized force in an opposed landing. But they don't have very long to do it in before the Big Crash--they are Enron with a few nukes. Russia is an example of what happens to a totalitarian regime that lasts long enough.
Are the Chinese upgrading their military? YES. Are the pros keeping an eye on it? YES. Do I panic because someone posts something from a Russian design bureau's product brochures? NO.
