I absolutely agree with you... but the Chinese etc do at least go through the motions of saying yes or no, whereas the Americans refuse to do so and therefore force the governments hand.
The whole thing is load of nonsense anyway. As far as I'm concerned, the whole nuclear-free policy is piece of luddite stupidity. I spent 16 years living within 10 miles of a nuclear weapons storage facility, and 25 miles from a nuclear power station, in a country where the risks are actually understood, and effectively managed.
"Nuclear -free" will keep us in the 20th century forever.
