The usa has the biggest army in the western world but china has the largest army globally. No one wants to piss off the chinese, why do you think that every country basically bows down to them. China only cares about itself, they dont concern themselves with other countries problems. Take the north korea situation, north korea gets all of its power from china so regardless of what north korea does no one will touch them because of its relationship with china. Presidents/prime ministers all tiptoe around china whenever trouble starts, do you really believe that north korea would have the armaments they have if it wasnt for china,s support? no they wouldnt, but no one is gonna -blam!- with china so all we do is bad mouth korea & show that we are upset with them. And until china believes that north korea have overstepped the mark then north korea are free to do what they want. China has all the power & they know it.
