AC contemplates the military utility of nonexistent weapons systems:
The UK will not give Ukraine any jets since it does not have jets to spare, but it will help Ukraine get F16s from other countries if they can find any, and then train them on them, although one problem there is the UK does not actually have any F16s to train them on. It sounds like we are at the point where we are now offering Ukraine imaginary weapons we are sure we will find someday.
Of course, not being a military historian / geomilitary strategist like myself, AC has clearly missed the salient issue here, which is the way those nonexistent weapons now being allocated to Ukraine were already been committed for non-use in a war with China over Taiwan island by RAND and the US military wargamers.
