The quantity and quality of their centrifuges makes it obvious they are enriching for a bomb now. The IAEA monitors alloys and key components for centrifuges. Certainly that is not perfect and there are some countries (maybe quite a few) that ok with Iranian bomb due to their latent antisemitism. But there are other countries that would get on board inspections and sanctions if Iran were given reactor grade fuel.
The deal that Obama and six other countries made with Iran (take note of which countries the others are) precludes any such thing. And nothing will stop Iran from getting a bomb anyway except eliminating the “Islamic Republic”.
