This is non-sense take a look at this link:
http://news.bbc.co.uk/2/shared/spl/h...tml/mining.stm
Especially where it says:
" reprocessing plant and a reactor to produce sufficient plutonium could be housed inconspicously in an ordinary-looking building."
I have seen pictures of the Israeli facility including a graphical video that shows all the buildings and the underground levels, the Israeli's have there entire program at one site, everything from enrichment to reactor to reprocessing the spent fuel rods, and the entire thing wasn't that big. Even the reactors can be hidden, and nuclear tests can be hidden in a country the size of Iran. I'll see if i can dig up that israeli video on youtube later. The largest maybe the enrichment facilities-but that can be broken up into smaller cascades or hidden underground.
and there is no evidence that the n.korean test "was a complete failure", we only know that there was a test.
I'll say this again, this is 1930's technology and there are Russian and pakistani and chinese scientists all over the place that would be happy to fill in any gaps that they might need. How do you think Pakistan was able to do it so easily 15 years ago, are they so advanced? Pakistan doesn't manufacture it's own aircraft and fighter planes, Iran does. Iranian missiles are longer range and they, not the Pakistanis are working on an ICBM. Iran has more oil revenue.
