I'd say it's Germany as well. They have the biggest and most technologically advanced economy. They will dominate Europe for a long time to come. Some might be tempted to say Russia, but their economy is in tatters and the fact that they have nukes doesn't really matter that much.
France and the UK also have nukes. German economy is tied to the Euro, with QE just being started for the Eurozone (Euro countries - not all of EU) that is targeted in the trillions of dollars, they may be dragged down significantly by the dead weight of the failed/failing Med and ex-Soviet states and this ongoing new debt. The UK actually benefits from this as their EU bills are significantly reduced (due to exchange rates) and the pound stay unaffected by the sell off - although it will hit EU the export market for British goods.
If the UK pull out of the EU in 2017 (referendum) - which is likely as it stands - then the full weight will be on German and French shoulders (economically) - it may well end the EU.
