"The Europeans are completely consumed with a battle to save the euro zone," says Ian Bremmer, president of political risk consultancy Eurasia Group. "It's a deep and ongoing crisis bigger than any they've experienced in decades... it's an environment where European leaders could hardly be expected to prioritise anything else."That could leave the continent being increasingly sidelined as emerging powers - not just the BRIC powers of Brazil, Russia, India and China but other states such as Turkey, Indonesia and South Africa - grow in importance.At the very least, it could undermine the ability of the continent's leaders to persuade the rest of the world to take them seriously on a range of issues, from trade to the importance of democracy and human rights."Europe probably isn't going to stop preaching to the rest of the world," says Nikolas Gvosdev, professor of national security studies at the US Naval War College. "But it's much less likely that others are going to be inclined to listen."
