A quick review:
I did oppose this invasion of Iraq by US forces without UN SC sanction.
I did write my representatives stating that. Repeatedly.
The ONLY reason to go was to enforce UN SC 1441, destroying Iraq's WMD capabiliites. This has not, as yet, been validated.
As Rip pointed out, however, once it starts the best thing is for it to be over quickly. I did indeed support that.
HOWEVER........
it is also pretty clear, with the rest of what is coming to light, that the Iraqi people were terribly and brutally oppressed and appear to be quite glad to be rid of Hussein's regime. I believe, as days pass, more and more Iraqis show that to be true beyond question.
