Defense Minister Ehud Barak warned Wednesday that if Iran acquires a nuclear weapon, it could try to attack the United States. Barak said the world should press Iran to stop it from building nuclear weapons. He spoke at a conference of the Institute for National Security Studies at Tel Aviv University. He said, "If it built even a primitive nuclear weapon like the type that destroyed Hiroshima, Iran would not hesitate to load it on a ship, arm it with a detonator operated by GPS and sail it into a vital port on the east coast of North America." Indicating the possibility of a military strike, Barak said, "We are not taking any option off the table, and we recommend to the world not to take any option off the table, and we mean what we say."
