Are the Ukrainians missing warheads or entire missiles? Do we know what type? Do we have part numbers? Inquiring minds want to know.
The warheads could be PM'd rather quickly with easy access to tritium.
IIRC the Ukraine had significant assets left to them by the dissolution of the USSR.
There is everything from nuclear artillery shells, land mines, warheads and whatever still over there, some in unguarded warehouses.
The Long range ballistic missiles are apparently look ed after, but the tactical nukes are a coin toss.
