North Korea's nuclear test and missile launches have Japan confronting a topic long off-limits: acquiring atomic weapons of its own. 'The threat is elevated and Japan should seek to arm itself with nuclear weapons,'Tamogami said in one of two recent interviews. 'North Korea will keep testing until they develop nuclear missiles that can reach the U.S.' (Photo by Toshiyuki Aizawa/Bloomberg via Getty Images)
