Obviously in lore wise it's "I need help. That's it"
Outside inspiration wise though, nothing says they can or can't be about Nuclear war though
Seeing all the theories and Divine Retribution's comment just put that funny little scene in my head of what would Regigigas think if presented with these theories.
One question about the theory: does it explain why exactly the Pokemon they used to represent the atomic bombing being based on golems. You know, the golem, as in the Jewish Mythical creature. If I'm understanding the theory correct, is suggest GF used a Jewish Mythical creature to reference an atrocity done to the Japanese people during WWII.

Well, it's a good thing during WWII Japan wasn't allies with a dictator who was committing genocide against the Jewish people which they knew about (though, to be fair, the Japanese did treat the Jews who had escaped to Japan better than in Europe even pushing back against most Nazi Germany's requests (still forced the Jews into a cramped ghetto)).

Also, many of the scientists who developed the atomic bomb were Jewish. So that adds a new layer where the Pokemon representing the atomic bombings are based on the mythical creature of people whom had a hand in developing the atomic bomb.

So, to get to the point, I'm kind of against the Regi Trio are related to the atomic bomb theory because, due to them using the golem, it's kind of super insensitive on multiple levels.
