Okay - answer this, primitives -
a ) Why would a country that is sitting on a gigantic field of oil be so determined to enrich uranium ?
b ) Why would a country build new uranium reactors when thorium is safer, more productive, and can't be weaponized ? - with the windfall of US money that comes with the deal, they could have easily went the thorium route and not have to worry about inspectors at all, as there would be nothing to inspect.
