President Obama's actually supporting it by closing an agreement with them.
While it is believed that Israel has possessed nuclear weapons since 1975, they neither deny nor admit to possessing any. It's widely believed that they are a nuclear power, although they have stated they will not be the ones to introduce nuclear weapons to the Middle East.
South Africa, Canada and Libya. South Africa developed six nuclear weapons under the apartheid government, but they voluntarily disarmed right before the fall of apartheid because 1) there would be no need for a country that wasn't white supremacist anymore to have nuclear weapons in Africa, and 2) they worried that the ANC might proliferate nuclear technology if they got their hands on it as they had a history of relations with leaders like Gaddaffi. Canada, long a major center of nuclear technology R&D, inventing the CANDU reactor and other pieces of nuclear technology, could have very easily developed nuclear weapons but chose an anti-nuclear stance and stated it wouldn't develop the bomb or allow other NATO states to station nuclear weapons on it's territory. Libya was very close to completing a nuclear bomb but Gaddaffi voluntarily gave up his nuclear program and let the US in to remove his weapons after Bush made an example of Iraq. He feared they'd invade and institute regime change in Libya to if he gave them the excuse of WMD program.
According to the UK Government's Defence Review undertaken in 1998, the UK maintains fewer than 200 nuclear warheads. Although the exact figure is not stated. Please see the related links.
At that time, there were no laws about using nuclear weapons but some people call the nuclear bombings a terror act. President Truman stated that Hiroshima was a military strong point but most of the people were civilians.
Israel is believed to be the sixth nation of the world to acquire nukes, anything further is plausible conjecture. It is believed that it developed the first working bomb prior to 1968. Some people believe that the 1967 Arab-Israeli war was ignited by the Arabs' fear that Israel was on the brink of going nuclear. As it turns out, Israel may have already developed the bomb before that conflict started but chose to defend itself conventionally. Estimates on the quantity of Israel's nuclear weapons is thought to range from 65 to 400. It is most likely around 250.
Under the United States policy of Proportional Response, an attack upon the United States or its Allies would trigger a force-equivalent counter-attack. Since the United States only maintains nuclear Weapons of Mass Destruction, it is the stated policy that the United States will regard all WMD attacks (Biological, Chemical, or Nuclear) as a nuclear attack and will respond to any WMD attack with a nuclear strike.
Iran
Um this doesn't make sense :P Thron? Are you bad with your english? I'm not making fun of you or anything but yeah... If you meant "thrown", the answer is no nuclear bomb has ever been thrown, they are much too heavy to throw. Even the lightest weighs about 50 pounds. At one time in the 1950s the army stated a requirement for nuclear hand grenades or nuclear mortar shells. However the labs quickly informed them of the impracticality and risk to our own troops of such weapons.
It is evident that Iran's efforts are focused both on uranium enrichment and a parallel plutonium effort. Iran claims it is trying to establish a complete nuclear fuel cycle to support a civilian energy program, but this same fuel cycle would be applicable to a nuclear weapons development program. Iran appears to have spread their nuclear activities around a number of sites to reduce the risk of detection or attack. This seems to be the reason.
No, the pills do not work and actually have a Warning Letter from the FDA regarding the misleading information based on their advertisements. It's so far been stated as having absolutely no real scientific data to back it up.
That's a difficult one. The Manhattan Project in WW2 consumed a great deal of US industry but I don't know if it affected the rest of the war effort. In any event it brought the war with Japan to an abrupt end so it may have saved money in the end. Later in the Cold War both the US and Soviet Union spent a great deal on building up and maintaining nuclear weapons, but I don't know if these costs have ever been stated, I doubt it, though the overall US expenditure on defence is presumably recorded.
No. If Iran were to build 3-5 nuclear weapons they could, although they would undoubtedly be destroyed in the process by Israeli nukes and US nukes. However, there is no evidence that Iran is pursuing a nuclear weapons program and no evidence that Iran hates another state enough to see its 5,000 year old civilization destroyed in the process. In essence, Iran does not currently have the capability, and even if it had the capability the assertion that it would do so is dubious. (except for the incidental fact that its president has stated publicly "the zionist cancer must be wiped off the map" etc.)
