The Telegraph reports that North Korea is under martial law (and this is different from every other day in Pyonyang exactly how?) and telling troops to "be ready for war" in advance of more nuclear tests.
If North Korea really wanted to protect itself, someone would take the government out to the site of the test, blow the government up, and let the people decide what was more important: food or nukes.
(Then again, I thought the same in the US in the 70s...and at other times when military spending was beefed up at the expense of other needs.)
