This response is utterly weak when considered in the context of retaliation against the attack on Soleimani. I am not saying this move is Iran's main retalitation but by itself its nothing. It is only a "fifth step" in Irans's reduction in its JCPOA commitment. All it says is Iran now removes its limit on centrifuge production. Iran is still abiding by the JCPOA (according to Iran) and is still in the NPT.
Look we don't know if Iran truly has nukes or not. We don't know to what extent Iran truly means its fatwa on nukes. All I will say is if this current Iranian regime truly does not believe in having nukes, then it simply deserves to be removed/wiped out due to this sheer incompetence. When faced with a rabid state like US ruled by someone like trump, only having the capability to wipe the US off the face of the map will truly protect you. If you don't believe this, then ask yourself this question. What is truly stopping the US nuking Iran if it decides to? The mutually assured destruction fear is NOT there for the US. An ancient nation like Iran should NOT allow its survival to be based on the decision making of some rabid fool like Trump.
