It's just because the risk (in my opinion). I mean, there's going to be this group of protesters and the govt today is a little off it's balance. I personally would like to see al gore in presidency today, but that didn't happen
I doubt Iraq would've happened and I doubt that the US would change it's focus to that. We really weren't in too big of threat (Except for 9-11 of course). We now found out there was no link between the two and since when is it our job to do the UK's search of nuclear weapons in Iraq?
