There is of course still a problem, alot of nations don't like the idea of being dependent on somebody elses technology for vital parts of the national infastructure (strange I know).
"Hi Mr Arab, want nuclear power, well then buy our plants."
"But they're ludicrously expensive."
"Well you wont have to maintain or build them, we'll do that all for you!"
"Wait, you mean you're going to build and man these plants with your own people?"
"Sure - what could be wrong with that, local jobs for foreign workers. Don't think about trying to work in our countries though, we wont stand for that."
"But we want to have our own people employed, what happens if our countires have a falling out?"
"Well then we shutdown the plant, take all our stuff and leave."
"I'm not liking the sound of this deal."
"Oh you also have to buy our increadibly expensive bespoke fuel."
"Wait you run the plant,your people build and run the plant, and we have to buy your over priced fuel?"
"That's about it."
"I think we'll pass."
"Fine darky, taste our bombs!"
It's like PFI on crack.
