Dumb title but it was a great movie.

The real meaning of Godzilla: Minus One’s title stems from what the titular monster represents in the film, and what Godzilla has symbolized in most iterations of the Kaiju outside of the Monsterverse. Godzilla was originally created as an allegory for nuclear warfare whose terrorization of Japan in most movies centered around the creature served as a metaphor for the horrors of war. Godzilla: Minus One reiterates this idea after the Monsterverse and Western media moved away from that concept, with the film being set in 1945 Japan.

The idea behind Godzilla: Minus One as the title is to indicate that Japan was at zero - the country’s lowest point - after World War II. From being on the opposite side of the war to the Allied powers of WWII to the nuclear attacks on Hiroshima and Nagasaki, Japan was in an incredibly dire state in the 1940s. In the film, Japan’s restructuring as a country is worsened immeasurably by the emergence of Godzilla and his subsequent attacks against the country, hence the title of Minus One as Godzilla’s wave of terror takes the country below zero
