Well, you guys asked for it!
Just some quick corrections before I post a theory on this tonight, though. Latvia is 4′7, which is just under 140 cm. The reason he gives for being so short is that Russia keeps pushing down on his head every day (I’ll argue that it’s more than just Russia). He actually says that he would be 10 cm taller.
Anyways, contrary to what other people have said before me, I do believe that there is a reason why Latvia is so short. There’s enough reasoning that falls directly in line with how Hima conceptualizes nationhood as well as their maturation process. I don’t think it’s fair to say that there’s no reason for this, as we’ve already seen how much thought Hima puts into his work, regardless of how weird it may get sometimes.
There’s significant evidence in the strips and character profiles. I’ll leave this one here, as it’s going to act as the backbone for my argument:
