FWIW: While he was at it, Clinton had the targeting cards removed from all ICBMs - do not know if they were ever restored.
It was just pointed out to me, correctly, that Bush Sr.’s Deputy Secretary of Defense signed the order on 2/92, to not allow service men or civilians to carry on base.
Pulling those targeting cards kind of makes sense if, like you say, they were put back.
Lot’s of new enemies out there.
