So I bet you're wondering post-G20: Is this the impending end of the world--or an opportunity for a cheap holiday in Greece next year? Even the experts can't say which way the global economy will go: If Greece quits the euro and returns to a devalued drachma, will Spain and Italy be forced to follow? Will Canada's "Little Toot" economy continue to chug along resiliently ahead of the U.S.'s sinking steamship? To help us make sense of all this, we welcomed aboard a new Huffpost contributor, EU expert Jeffrey Cimbalo. His latest post declares the G20 an abject failure. Hmm. Don't start googling discount Olympic Air tickets yet.
