Israel's non-signatory status in the Treaty on the Non-Proliferation of Nuclear Weapons, combined with their refusal to admit the obvious truth of having nuclear weapons despite their not-so-coy threats of using nuclear weapons all combine to paint an unambiguous picture: Israel is a rogue state. They are dangerous; a threat to world peace.

To their credit, Russia, China and the USA are all signatories. Israel, North Korea, Pakistan and India are not (what wonderful company Israel finds itself in!); they are all rogue states. Of those all four have border disputes, all four have nuclear weapons, and all four have made themselves a threat to world peace. Of these four, Israel is the only one that continues to lie about having nuclear weapons.

If Israel does not qualify as a "rogue nuclear nation", then the term has certainly been diluted.
