Japan will possess its own nuclear missiles by 1st January 2020.
The claim will be considered true if either of the following two events occurs:
a) a minister of the Japanese Government, while in office, states publically that Japan possesses nuclear missiles and this claim is not denied within one calendar year by either the Japanese Prime Minister (if one exists) or the Japanese Head of State (if one exists); or
b) it is alleged in a publically available speech to the United Nations by one of the current five permanent members of the United Nations Security Council (US, UK, France, Russia, China) that Japan has nuclear missiles and this statement is not publically denied within one calendar year by either the Japanese Prime Minister (if one exists) or the Japanese Head of State (if one exists).
The claim will be considered false if neither of these conditions is satisfied even if it is generally believed that Japan has nuclear missiles. It will also be considered false if Japan ceases to exist as an independent unitary state controlling at least the island of Honshu.
If true, the claim will pay $1 on the judging date, otherwise the claim will pay $0. The decision of the judge will be final.
I will judge based on the wording of the claim unless it is found to be ambiguous. Such ambiguities will be resolved based on my perception of the author's intent.
