Why did you not include Israel in your list of countries with nuclear weapons (11 January, p 17)?

• While figures for Israel’s nuclear stockpile were not included in the data from the Natural Resources Defense Council on which we based our table, best estimates, such as the those produced by the Federation of American Scientists, suggest the country currently has between 100 and 200 nuclear warheads.
