Sometimes when I’m bored, I’ll do some google maps “tourism”, and just cruise the globe. One of those spots I’ve visited, is right at that tri-border with Russia, N. Korea, and China.
I always thought it was weird that China doesn’t have a direct shore/port on the Sea of Japan. It doesn’t really look like the Tumen River would cut it to give sea faring ships access either. Annexing Vladivostok would fix that.
I read that as “all five are the same”. And I’m like damn, don’t want to work in a slaughterhouse if that’s true for you!
