Given that George W. Bush's failures are magnified by his recency, he still has to be ranked among the worst.
I wrote this prediction on FR less that 48 hours after the successful enemy attack on the WTC (I had met W during the 2000 campaign in NH, Summer of 1999, and I was very unimpressed).
As I predicted, he chose to fight a Vietnam war in South Asia, the evil consequences of which are still with us,
I disagree with that assessment. He covered that place up and it was a hard fight. We had it. Obama gave it up.
