Narrative:

Prior to coasting out westbound; our left windshield cracked; spreading like an alligator hide across the entire windscreen and producing an ECAM for windshield anti-ice failure. There was evidence of burned wires etc. In the windscreen. We initiated an emergency descent; called the relief pilot back to the flight deck and coordinated a diversion to the nearest suitable airport; which was approximately 200 miles away; where we landed uneventfully; although over ZZZZ.
