Developing ballistic missles + long range drones= nukes on the table.
large quantities of a fissionable material suitable for enrichment was (and possibly is) already on hand in Ukraine
In wartime Ukraine, the possibility of nuclear research and development work being performed, or storage of plutonium in quantity suitable for enrichment, beyond IAEA overview, cannot be excluded
