Most countries did not become nuclear powers! The UK and Russia followed after the US within about 5 years I think, though I have not checked dates. Then France and China somewhat later, and Israel, India, and Pakistan after that.

Israel is the only nation in the Middle East known to have nuclear weapons.
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.
Afghanistan has not argued that it wants nuclear weapons.
The United Kingdom tested its first nuclear weapon on 3 October 1952.
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.
Nuclear technology was used to power many things.
No, Israel designed their own.
Israel has never made threats against Iran, while the Iranian government has made it very clear the destruction of Israel is their ultimate goal.
