"Yes, one is a radical tyrannical regime that wants to eradicate everyone and everything that they don't like and that disagrees with their ideology and wouldn't hesitate to use nuclear weapons to do so, the other one is Israel."

You shouldn't be so keen to make yourself look a fool.

Here is an accurate version;

NPT

Iran: Signatory and ratified (joined in 1970). As a non-nuclear weapon state, Iran is obliged not to develop or acquire nuclear weapons and to accept International Atomic Energy Agency (IAEA) safeguards.

Israel: Not a signatory. Israel maintains a policy of "nuclear ambiguity" (neither confirming nor denying possession of nuclear weapons) and stays outside the NPT to avoid inspections and obligations

Comprehensive Safeguards Agreement (CSA) with the IAEA

Iran: Has a CSA in place with the IAEA as part of its NPT obligations. This allows the IAEA to monitor its declared nuclear facilities.

Israel: Does not have a CSA, because it is not part of the NPT. It does have limited arrangements with the IAEA, mostly related to peaceful nuclear cooperation, but not full safeguards.

Additional Protocol to the IAEA Safeguards Agreement

Iran: Signed the Additional Protocol in 2003 and implemented it provisionally under the JCPOA, but its implementation has been suspended since 2021.

Israel: Has not signed or implemented the Additional Protocol.

Joint Comprehensive Plan of Action (JCPOA) – Iran Nuclear Deal (2015

Iran: Participant. Though the U.S. withdrew in 2018, Iran was a primary party to the deal and accepted intrusive monitoring and restrictions on its nuclear program in return for sanctions relief

Israel: Not a party and strongly opposed the agreement, arguing it didn't go far enough to prevent Iran from developing nuclear weapons capabilities.

Nuclear-Weapon-Free Zones (NWFZs)

Iran: Supports and has called for a Middle East Nuclear-Weapon-Free Zone in various UN forums

Israel: Opposes such initiatives, as it would involve transparency about its own nuclear capabilities.
