Will Silvio Berlusconi resign? Author Niall Ferguson on what went so wrong in Europe

Just as Greece begins to get a handle on its debt crisis, another European country stands on the brink of crisis. There are reports this morning that Italy's Prime Minister Silvio Berlusconi will resign. On Saturday, tens of thousands of demonstrators gathered in Rome to voice their opposition to his government and its reforms. A crucial vote on budget reform measures is expected in Rome Tuesday.

Niall Ferguson, author of "Civilization: The West and the Rest," explains to Christine Romans why Berlusconi needs to step down.
