Yup, not EVERYTHING will be revealed to us, no need for EVERYTHING, but there are other reason why we need to know certain things. Remember, a lot of people stationed in Korea (US troops) went over, and we had some things regarding the recent war with Afghanistan. THis is the reason why I say I know some.
HOwever, we work VERY closely on matters regarding China and North Korea. (They are our neighbours after all

) That was the whole point that got me worked up, issues that were discussed regarding China, and how some seem to think China's a clown, and the North suddenly had possible nucleaer plants. WE know more about North Korea than does the US, and we don't tell them everything, but important facts must be revelaed by both parties.
THink of it like this, valuable info is like chips on a gambling table. You give out one, and the other gives out another. That's how it works here.
Regarding China, military positioning is known to ALL countries, and China doesn't hide much about it. If some still think that China can be played by the US, we are doomed. Luckily, the ones who are in power aren't ignorant.
I leave this reply with the following:
Any country needs a good reason to go to war, in order for the UN and for the world's people to accept the declaration. If there is/are no suitable reason(s), one simply makes one up, or bloat it up to such an extent that people feel a war is the only means to an end, solely for their benefit. No, benefits are not discussed in public either.
