OK, can you answer the part about the Uranium then? Also, in times of war, who the heck cares about agreements? Things can be done in secret.
Didn't I do in previous post? Yes Japan gets it's Uranium from other countries such as France (Areva), while the Uranium ore is produced in countries such as Kazakhestan or Niger, the countries that does the enrichment necessary for it to be useful in nuclear power plants are France, Germany, Netherlands, UK, USA, and Russia with France being the leader in this domain to my knowledge. Japan gets it's Uranium from these countries, and the whole circuit from production to delivery is controlled as enriched Uranium is no joke. Usually it's 5% enrichement for Commercial Uranium, and the maximum allowed with AIAE is 20% for medical use
