(V):   Do you mean an investigation of the events leading up to the war in Iraq?  If a trustworthy investigation could be conducted, I wouldn't oppose that.  But what can be accomplished by it?

I'd rather see a complete revamping of the US's foreign policy with respect to military presence in other countries.  We have plenty of probems on our own soil and ought to be attending to those first.  I don't know what a good Foreign policy would look like but I think we can do much better.
