The guy is an idiot but I guess he knows something about nuclear submarines. If you're Turkey or Israel or Saudi you don't want nuclear subs, and he must have known that. Nuclear subs don't make sense over diesel+AIP in the Med or the Persian Gulf or Red Sea - these seas are too narrow or too shallow, so nuke subs would be detected much sooner, cost much more, and be far larger. Having longer trips does not cover all these drawbacks for countries that must base in these areas. Nuclear subs are for blue-water navies, not green-water navies. Iran/Russia/China are out for reasons pointed out elsewhere in the comments. UK wouldn't need translation (though the idea of 'translating' a spynote into Chav is IMHO incredibly amusing). South American governments obviously don't have money for this. That leaves us with France or - more exotically - Spain/South Korea/Japan. The latter three don't have nuclear subs, but wouldn't be entirely mad to consider them. However, if the recipient has an existing industry, France is the only remaining logical contender.
