Russia, China, and the US start proxy wars and bomb the shit out of the mechs belonging to smaller, less powerful countries.
Lets say, for the sake of things, each one is exactly the same. You can use the Zaku as a base model if you're a Gundam fan, or another if you'd prefer, but each country has exactly one.

After the Earth is devastated by everyone fighting, the surviving countries will come together and decide to hold a tournament every 4 years. Each country will send its mech in, and the last one standing gives their respective country the right to rule all others for the next 4 years.
Hmmm, where have I heard this before...
