I would be impressed if they risk it. Literally half of Mongolia’s population resides in their capital city Ulaanbaatar. If a country bordering Russia were to arrest the sitting Russian president and turn him over to Copenhagen then there’s a non-zero possibility of a retaliatory airstrike on the capital, destroying their only major city and killing a significant percentage of the entire country’s population.
If you are taking requests, I am curious how ridiculous The Longest Journey would be.
