I agree the that the second Iraq war was a mistake. At least McCain is admitting his part in it.
I used to believe that Bush did what was then the right thing based on the best Intel available to him at that time. After having gotten to know the swamp, I don’t believe that any more.
John McCain knows it’s Bush/Cheney who will bear all the blame.
Hillary also claimed that she made a mistake, she voted for the Iraq invasion.
