Greece Is 'Playing Hardball'

"Greece wants bargaining chips and it's playing hardball with the rest of Europe. It's obviously not getting what it wants in these discussions. That is ultimately the way that a political union or a continent that is on a path towards political union should work," Stephen Gallo, head of market analysis at Schneider Foreign Exchange told CNBC Monday in a discussion on Greece's threat to pull out of the euro. He added that a Greek exit would "create havoc" in Europe.
