That's crazy and some of these people will actually blow a country off the map. I think that's why the United States has also been involved with all this.
In fact, the 9/11 attacks were carried out by the same people, and it was only a tiny scale terrorist attack. Although probably people in several countries helped to make them happen.
Israel is under direct protection of the US, and that's why the US is a target for those people.
They not only want to wipe Israel off the map, but the US as well, just for that reason.
Yup, that's not good as well. I didn't know Pakistan had nuclear weapons though. If Iran got them, **** would hit the fan fast. Aren't they trying to get them though? Nuclear weapons are never good because they could destroy the whole world.
The US was the first -- and so far only -- country that ever used nuclear weapons. Two bombs on Japan in 1945 wiped out the cities Hiroshima and Nagasaki, which effectively ended the Second World War.
So far, the deterrence power of nuclear weapons has prevented a Third World War.
However, if there's a group of people with no qualms of using them,
even if they irradiate their own people in the process, things might become very dangerous.
Some people might speculate about attacks and counter-attacks and don't view nuclear weapons as such a great danger. This is when things could become terrible ... b/c if one group thinks it can use them with
tolerable losses on their own side, then things can turn ugly.
To give you a picture: A modern nuclear hydrogen warhead (ignited by a plutonium warhead) has the power to directly destroy an area of at least 50 - 100 km ( 31 - 62 mi ) in diameter. The radiation will spread over several hundred or thousand km (or mi), however, to various degrees. The more bombs are being used, the higher the danger is for other people on the planet.
For example, in-air nuclear bomb tests in the 1950-1960ies have shown that fish all over the planet became irradiated, that's why those type of tests have been banned.
