At most, I've seen reports that Iran is enriching uranium to 60%, well below the threshold required to produce nuclear weapons (which requires 90% U-235, minimum). So, why would Iran be enriching uranium at all? Well, Iran uses nuclear power. Once a spent fuel rod is used in a nuclear reactor, it can be enriched, over and over again, so it can be reused, until roughly 98% of the mass is gone, converted to energy in the reactor. France does this, as they get most of their power from nuclear.

In contrast, the U.S. and Japan don't re-enrich the spent fuel rods, and through monumental stupidity and corruption, we keep our spent fuel rods in cooling tanks or behind chain link fences, where they will sit there in perpetuity. The U.S. actually had a decent plan to store our nuclear waste, and spent billions to build the Yucca Mountain facility, but Obama nixed it, and it's just been sitting there ever since, completed and yet doing nothing (officially). This also caused the radiation leakage from the Fukushima plant after the 2011 earthquake in Japan. The reactor didn't leak any radiation, as they're built incredibly well. It was the spent fuel rods sitting in cooling tanks which leaked radiation.

In any case, I agree with other commenters here. Iran has every right to build their own nuclear weapons. The only belligerent state with regard to nukes is Israel, who stole from the U.S. to get their nukes, and refuses to sign the nuke treaty which all other nuclear nations have. The excuse that "we can't allow a Muslim nation to get nukes" is also complete bullshit, as Pakistan has nukes, is majority Muslim, and hasn't used nukes (yet). The fact that Israel hasn't been properly sanctioned, punished, and "liberated" by the U.S. because of their stolen nukes is further proof that the U.S. is controlled by jews.

[correction] Japan apparently does re-enrich their spent fuel rods, but it wasn't enough to protect themselves from the 2011 disaster, due to how the spent fuel rods were being stored prior to re-enrichment.
