Passed on to me by a friend about a post last week:

If a thorium reactor, among other things “created no weapons-grade by-products,” and Iran wants nuclear reactors simply “to establish plete nuclear fuel cycle to support a civilian energy program,” as it claims, perhaps we could set it up so that potentially dangerous regimes like Iran can use thorium and not uranium based nuclear reactors.

As Tim Dean highlights the possibility in the Cosmos article: “Imagine the West offering thorium-fuelled ADS reactors to countries such as Iran or North Korea: this would satisfy their demands for cheap nuclear power, but entirely avert the risk of the civil nuclear program leading to the development of nuclear weapons.”
