Neither should Israel.
The IC continues to assess that Iran is not building a nuclear weapon and Supreme Leader Khamanei has not authorized the nuclear weapons program he suspended in 2003. The IC is closely monitoring if Tehran decides to reauthorize its nuclear weapons program. In the past year, we have seen an erosion of a decades-long taboo in Iran on discussing nuclear weapons in public, likely emboldening nuclear weapons advocates within Iran's decision-making apparatus. Iran's enriched uranium stockpile is at its highest levels and is unprecedented for a state without nuclear weapons.
And my personal opinion, which is correct, NO ONE should have nuclear weapons. Not the US. Not Russia. Not China. Not the UK. Not France. Not India. Not North Korea. Not Pakistan. NO ONE! Further, Israel (along with Pakistan, North Korea, and India) has not signed the Nuclear Non-Proliferation Treaty (NPT), despite international pressure to do so. Israel won't even say how many they have. That's probably because they are stolen.
Good luck getting them, they actually work.
