That story makes no fucking sense.

The nuclear material came from an unidentified leader of an "ethnic insurgent group" in Myanmar who had been mining uranium in the country, prosecutors said. Ebisawa had proposed that the leader sell uranium through him in order to fund a weapons purchase from the general, court documents allege.

Prosecutors said samples of the alleged nuclear materials were obtained and a U.S. federal lab found they contained uranium, thorium and plutonium, and that the "the isotope composition of the plutonium" was weapons-grade, meaning enough of it would be suitable for use in a nuclear weapon.

1. You cannot mine plutonium

2. any plutonium is weapons grade

3. They likely found some rare plutonium atoms in a pile of uranium and thorium.
