But how do the current negotiations permit that? How will Iran build a bomb if they are required to reduce current supplies by 97% and not enrich over 3% when 90% is required to build a bomb?
See above
90% required, less than 3% allowed. How will they build a bomb with only 3% enrichment?
Also, you seem to think the deal is based on trust.. Completely wrong. All of Iran's nuclear facilities are subject to inspections and the sanctions don't see relief until they pass initial inspections of all facilities and the sanctions can snap back into place at any time if they violate the terms of the agreement, so why would they agree to the deal only to avoid their responsibilities? They wouldn't, there would be no point.
Everything you're saying is categorically wrong
