Fareed Zakaria talks to Nobel Prize winner Paul Krugman. Why does Paul Krugman say space aliens could fix the U.S. economy? Paul Krugman: Think about World War II, right? That was actually negative social product spending, and yet it brought us out. If we discovered that space aliens were planning to attack and we needed a massive buildup to counter the space alien threat and ... inflation and budget deficits took secondary place to that, this slump would be over in 18 months. And then if we discovered, oops, we made a mistake, there aren't any aliens, we'd be better - there was a Twilight Zone episode like this in which scientists fake an alien threat in order to achieve world peace. Well, this time ... we need it in order to get some fiscal stimulus.

Each news summary is created according to strict standards. Here's how we do it.
Each summary is created using a consistent editorial procedure. The target length is approximately 16 lines of 11-point Arial text in a 650-pixel-wide column. Up to 25% of a summary may be set in bold to emphasize the most important ideas. Summaries are composed of verbatim excerpts presented in the same sequence as they appear in the original news source, with very minor editorial additions. Where material has been omitted between excerpts, the omission is indicated with ellipses (...). Any words added by an editor for clarity or context appear in [brackets]. Our original news editor was Fred Burks. Tod Fletcher edited most summaries from 2007 through 2014, and Mark Bailey has served as news editor since 2014.
