U.S. policymakers should highlight Japan's possible nuclear pursuit and other security repercussions for China in pressing Beijing to stop North Korea from testing its nuclear weapons, a Senate Republican policy panel said in a recent report."A test in North Korea would certainly raise the prospect of a major public debate in Japan over whether to turn its latent nuclear capabilities in its civilian and space sectors into an overt nuclear weapons program," the U.S. Senate Republican Policy Committee said. As a paramount policy option, the United States must "essentially" demand that China "make a choice: either help out or face the possibility of other nuclear neighbors," according to the report.
