On Friday, North Korea tested a missile than can deliver a nuclear weapon to almost any target in the continental United States, marking a major accomplishment for a state than many thought was on its last legs in the early 1990s. But far from dead, North Korea has managed to evade every political, military, and economic barrier that five successive U.S. presidents put in its way. Now, the United States under President Donald Trump has a massive but surmountable challenge on its hands—deterring a nuclear-armed North Korea and preserving and strengthening America’s alliances with South Korea and Japan, countries currently questioning whether Kim Jong Un’s new capabilities might prevent the United States from coming to their defense.

The risk of nuclear proliferation has always been the chief objection to reprocessing but proponents argue that today, with uranium enrichment technology more easily available, reprocessing no longer represents an efficient route toward nuclear weapons...
