G-20 summit helps unite US, Europe and Russia against scourge of ISIS

G-20 summits are usually dominated by economic issues. But the latest meeting of the group held in the historic Turkish city of Antalya which was concluded on Monday focused more on terrorism and security - appropriately and understandably so.

The overall outcome of the Turkey summit was encouraging, all the more for the fact that it produced a rare meeting of minds between the leaders of the United States and Europe on the one hand and Russia on the other.

There was certainly no dearth of economic issues worthy of discussion in Antalya. The eurozone is still reeling from recession. China's economy is slowing, sending ripples across the developing world as well as commodity markets. Japan has fallen back into recession. Commodity exporters such as Australia, Brazil, Russia, Indonesia and Malaysia face challenges that could be prolonged.
