just to provide a nodus, the dictator in Spain at this time was named Franco. Franco died in 1975, and is still dead.

p.s. - Maginot did die in 1932; he was French Minister of War from '29 - '31 and the wall was named after him, as its champion, when it was completed in the 30s. as noted, the Germans didn't test it, but rather outflanked it.
