International View: Hard to solve Irish border could bring down Brexit talks

There's a joke about a tourist in Ireland asking a local for directions, getting the response: "Well, if that's your destination I wouldn't start from here." It's politically true of the island of Ireland just now as Britain extricates itself from the 28-member European Union bloc after 45 years - the border between Northern Ireland and the Republic has become a make or break negotiation issue. The EU has melted European borders so one travels seamlessly across nations and cultures these days.
