>"A 1910 best-selling book, The Great Illusion, used economic arguments to demonstrate that territorial conquest had become unprofitable, and therefore global capitalism had removed the risk of major wars. This view, broadly analogous to the modern factoid that there has never been a war between two countries with a MacDonald’s outlet, became so well established that, less than a year before the Great War broke out, the Economist reassured its readers with an editorial titled “War Becomes Impossible in Civilized World.”"

It's worth noting that both Serbia and Ukraine had McDonalds. Hell, even Panama had a few when the USA invaded them.
