The uber-plush Burgenstock resort perched high above Switzerland's Lake Lucerne provides the dramatic setting for Friday's planned signing of the US-Iran memorandum of understanding to end nearly four months of war. The luxurious hotel complex -- hard to access and therefore easy to seal off -- was proposed by Washington and Tehran as well as their Pakistani and Qatari mediators, Switzerland said Tuesday. The tranquil and picturesque location, with water on three sides, is well-accustomed to hosting world leaders, movie icons and peace talks.
