Article 103 Charter of the United Nations : “In the event of a conflict between the obligations of the Members of the United Nations under the present Charter and their obligations under any other international agreement, their obligations under the present Charter shall prevail.“.

This explains why any State bombed with depleted uranium weapons, even in principle bound by NPT rules, is allowed to reply with plutonium 239 transmutated from that depleted uranium. This is a general principle translatable of course to e.g. thorium 232 strikes and uranium 233 retaliations, or to americium strikes and americium 245 retaliations (etc.).

Here’s as complement the argument of the “safeguard measure” that represents highly enriched uranium stocks against depleted uranium strikes. That’s the conclusion of the reply to another point brought to Gemini.
