I'll answer, but this will really confuse you.
At this time, I feel my government has acted correctly in BOTH instances.
Unlike some prescient folks here that have already decided that SH didn't have WMD, I'm willing to wait and see what SH himself has to offer on the subject.
So, in the case of Iraq, my government deemed it an "immediate threat" and acted. I expect them to act on "immediate threats". Further, I'll give them the benefit of the doubt on that for a few more months. Let them squeeze SH a bit and see what develops.
Now, at a later date, it may be definitively shown that SH had no WMD. If so, I'll have an extremely different view of this administration's actions against Iraq.
In the case of Korea, they've done exactly what I think is correct and the process proceeds. The day may come when it is resolved peacefully..... or the NK's may do something stupid and initiate their own vanishing act from the face of the earth. You never can tell with lunatic dictators. Some give up without firing a shot, some shoot themselves, others try to take the world down with them. So, it's playing out in a positive fashion so far. What's not to like?
