Was the euro ever "about to collapse"?

Hong Kong (CNN) -- Less than six months ago, eurozone watchers had been predicting the breakup of the 17-member bloc of nations as the euro plunged to a 25-month low against the U.S. dollar last July.

Even as recently as November, Warren Buffett, the famed CEO of Berkshire Hathaway, said of the eurozone's future that "it's hard to tell exactly how it comes out."

But since then, the euro has appreciated nearly 11% as its member countries battled to contain sovereign debt crises, rising unemployment and social unrest. The euro now stands at a 13-month high against the greenback.
