The European Union building on New York's Third Avenue is an office tower with a glittering facade and an impressive view of the East River. Chris Matthews, the press officer for the EU delegation to the United Nations, opens the ambassadors' room on the 31st floor, gestures toward a long conference table and says: "This is where all ambassadors from our 28 members meet every Tuesday at 9 a.m." It is the place where Europe seeks to forge a common policy on the UN.

To mark the official opening of the delegation's new offices in September 2012, EU Commission President José Manuel Barroso and EU Council President Herman Van Rompuy flew in from Brussels, and UN Secretary-General Ban Ki-moon was on hand as guest of honor. For "old" Europe -- which finances over one-third of the regular UN budget -- this was a confirmation of its geopolitical importance.
