Ah, yes! Dumb like the man who wrote more than any other 20th Century president--Ronald Reagan.
No they won't. They'll join the parade at the end and say they were for it all along. Or they'll say that their principled, nuanced, intelligent, etc. criticism of the administration forced a better approach, which led to the great success. Or they'll say that if we had only used their preferred approach, we would have reached the same conclusion, only with less money or less loss of life. They'll say whatever they want, and the VLWC will join in and support their story, whatever it turns out to be.
They're the most cynical of opportunists, waiting to see what the outcome will be so they can decide what they were for. They are playing politics with American (and other) lives, and they are traitors.
