At the present, Iran is in a state of nuclear latency. In other words, it possesses the materials needed to build nuclear weapons should it decide to do so.
Iranian leaders have routinely claimed that they have no intentions of militarizing their nuclear industry.
Historically speaking, public polling dating to the middle of the 2000s has consistently shown that although Iranians are in favor of a civilian nuclear program, the majority of them are against the development of nuclear weapons.
That said, recent polling hints at Iranian citizens warming up to the idea of the Islamic Republic becoming more receptive to the idea of possessing nuclear weapons.
