So who gives the right to one country to own nuclear weapons and enrich uranium and not to another?
Honestly, I dont want to hear argument "We will not use it." Im sure everybody remembers Hiroshima and Nagasaki and if WW3 came along those weapons would be used again.
Doesn't Israel have a nuclear bomb?
Yes. Israel, however, is not a party to the NPT, so is not obliged to report to it. Neither are India or Pakistan, both of which have developed nuclear weapons. North Korea has left the treaty and has announced that it has acquired a nuclear weapons capacity.
On 18 September 2009, the IAEA called on Israel to join the NPT and open its nuclear facilities to inspection. The resolution said that the IAEA "expresses concern about the Israeli nuclear capabilities, and calls upon Israel to accede to the NPT and place all its nuclear facilities under comprehensive IAEA safeguards... "
Israel refuses to join the NPT or allow inspections. It is reckoned to have up to 400 warheads but refuses to confirm or deny this.
