Thomas Friedman: Nukes, debt and climate--which will kill us first?

"This moment reminds me of an image John Holdren, the president’s science adviser, uses when discussing the threat of climate change, but it also applies to the dollar: 'We’re driving in a car with bad brakes in a fog and heading for a cliff. We know for sure that cliff is out there. We just don’t know exactly where it is. Prudence would suggest that we should start putting on the brakes.'”
--Thomas Friedman
