Despite a lot of sensible, if misdirected, opinion on here, you all seem to have a peculiarly selfish focus.
The new world order cares not what you were trained to defend against.
You can all make all the noise you want about Russia, China and Syria.

Sometimes, when you look so closely at the bigger picture, you don't see what's right in front of you.
