Well, I read this:-
This month's rocket launch by reclusive North Korea shows it has likely developed the technology, long suspected in the West, to fire a warhead more than 10,000 km (6,200 miles), South Korean officials said on Sunday, putting the U.S. West Coast in range.
So, how far are Iranian missiles from the U.S.?
Should that worry anyone in the U.S.?
Well consider this from this past September:
Iran and North Korea signed a scientific and technological cooperation agreement Saturday, bringing the two nations deeply at odds with the U.S. closer together.
Iranian state TV did not provide further details on the document but said it will include setting up joint scientific and technological laboratories, exchange of scientific teams between the two countries and transfer of technology in the fields of information technology, energy, environment, agriculture and food.
Any technical accord between Pyongyang and Tehran is likely to raise suspicions in the West.
Think again, Obama.
