Five years after Bush's ill-starred invasion of Iraq, three years after Hurricane Katrina and seven months into the unravelling of the U.S. financial system, the point is that the 43rd president of the United States – regardless of his ranking in the pantheon – is a unique and unmitigated disaster.
Among U.S. historians, it has become great sport to rank the country's presidents. Bush vies with many for the title of absolute worst – from Ulysses S. Grant, who oversaw a post-Civil War era so corrupt it was known as Grant's Barbecue, to Richard Nixon of Watergate fame, to Herbert Hoover, the hapless president in charge during the stock market crash of 1929.
But Grant, Hoover and even Nixon did not do as much damage worldwide. Americans may still be debating Bush's legacy. I suspect the rest of the world has made up its mind.
