December 4th, the Italian Referendum.

Today, December 4th, 2016, the Italian people will hold a referendum vote to decide on whether or not to concentrate additional power with their central government. A "yes" vote will do just that, and will also be a vote of confidence in the Eurozone and the Euro currency. A "no" vote will basically be a giant middle finger aimed straight at Brussels and the EU and will open a window to Italy's dropping the Euro.

All indications in Italy point to a victory for the "no" camp.

Zerohedge (in the above link) posits that this could lead to a worldwide economic crash like none ever seen.

The house of cards isn't going to stay up forever.
