Can we ask questions?

I was wondering about an article I saw wherein the U.S. added additional materiel to the missile defense system without fully informing/confirming South Korea/Japan (of course, I cannot find the articles anymore, my luck) Can anyone confirm/disprove this? It doesn't seem like the end of the world or anything, but it also seems like it should have been a basic bureaucratic step in the process. Didn't know where else to ask this.
