While campaigning for the abolition of nuclear weapons as the sole country in history to suffer a nuclear attack during warfare, Japan has continued to rely on the U.S. nuclear umbrella for its own security — and opposed the U.N. treaty banning nuclear weapons on the grounds that such an accord without the involvement of nuclear weapons states would have little effect on nuclear disarmament. Survivors of the atomic bombings of Hiroshima and Nagasaki called this week on the government to endorse the nuclear ban treaty. But Prime Minister Shinzo Abe, attending the ceremonies in both cities, reiterated that Japan will seek to contribute to the goal by serving as a bridge between nuclear weapons powers and non-nuclear weapons states — although concrete results from such efforts do not appear to be on the horizon.
