Stopping petty little dictatorships before they really hurt someone
We know NK has WMDs, there is no ambiguity here. Do we want to wait
around for them to drop a crude nuke on the US West Coast before we
do something about them?
The number of petty little dictatorships seems to be growing, not shrinking.
The US has the right and the necessity to stop them. Just ask the people
who have to live in them every day how they feel about their current
leaders - oh wait, you can't.
No, they don't have to then follow our kind of freedom, but they do deserve
the right to choose the kind of freedom they want.
