In the context of the Cold War, Canada sent Inuit families to the far north in the High Arctic relocation, partly to establish territoriality. The Canadian monarch, Queen Elizabeth II, accompanied by the Duke of Edinburgh, Prince Charles, and Princess Anne, undertook in 1970 a tour of Northern Canada, in part to demonstrate to an unconvinced American government and the Soviet Union that Canada had certain claim to its Arctic territories, which were strategic during the Cold War. In addition, Canada claims the water within the Canadian Arctic Archipelago as its own internal waters. The United States is one of the countries which does not recognize Canada's, or any other countries', Arctic archipelagic water claims and has allegedly sent nuclear submarines under the ice near Canadian islands without requesting permission.
