By mid-1960’s knowledge and fear of nuclear weapons was widespread
With increased fear….public began push for greater limits/disarmament 1968-Nuclear Nonproliferation Treaty (NPT) Reduced # of weapons arsenals Some nations have abandoned nuclear weapon programs/others have defied
“New Start” Treaty signed btwn. US—Russia (2009) Severely reduces the # of arsenals on both sides by 1,550 warheads or 700 nuclear launchers
Although US and Russia have made great limits---biggest fear lies primarily in four nations: Iran—Publicly wishes to have nuclear power-- -many fear they are developing weapons Syria---Increased Palestinian/Israeli tensions Israel---Who will blink first? North Korea—recently deployed long-range propulsion rockets---where could they reach?
