I agree with you that Iran and North Korea definitely don't seem to be a threat against Western Europe, at least not an initial one or immediate one. I was under the impression that the locations for the shields were chosen based on it being able to intercept a multitude of possible strikes against different countries. Obviously the information I've gotten has been minimal and not well researched, which is why I continue to pester you ;).
Given the information you've provided, it seems Obama was indeed making a good decision, that's good news. I am a little curious on what the real threat is already against the US though. It's arrogant to think that we're not being targeted for a large hit, but with the media the way it is it's hard to accurately gauge anything, I tend to err on the side of being overly critical.
