Let us know how it turns out!
If that referred to World War I, well, a little backstory to that s/s:
China had long ago vassalized Aztec. Egypt had this weird on-again-off-again vassalization thing with Inca, so I think it was a voluntary vassalization and not capitulation.
I couldn't believe it when I saw that Ghandi had finished Apollo when I didn't even have Rocketry yet. China, the 800-pound gorilla of the big continent who had already vassalized Montezuma, was big but also a little behind technologically. So I bribed him with a tech to fight India to slow India's spaceship construction. Unfortunately China steamrolled India pretty quickly and vassalized it. And India just kept building SS parts! Worse, other civs were starting to get Apollo.
Result: I had to trigger World War I in the hopes that it would slow them all down. The China-Aztec-Indian team took on the Egypt-Incan team, and I also bribed China to attack Japan which was isolationist, to make it a fairer fight. But I think they might have had a DP with Egypt anyway; I can't remember, this was one of my older s/s when I was still learning the game.
Instead of slowing down the big continent, I just gave China an excuse to eat everyone. China started with Egypt, which lost three cities before it capitulated to China. That broke the Egypt-Inca vassal relationship, and Inca became a noncombatant, not that it mattered since they were too far behind to be a real Apollo threat anyway. China then turned to Japan and ate some cities, so Japan became China's vassal.
The game ended with my spaceship launch at some really late year like 1966 or something because I had mismanaged my island and to make matters worse, I was way behind due to the isolated start (no tech trades, no tech discounts for knowing civs that already have techs that I've not yet researched). However, nobody else had the more advanced SS parts built by the time I launched, because of World War I and the ensuing chaos. China did have a whopping FOUR vassals by the end of the game, though: Aztec, India, Egypt, and Japan!
