It's weird how you want to pivot from separatists being propped by their 'big brothers' to "they weren't using exactly the same weapons so it doesn't count".

Nazi's were certainly using armed provocations to provoke the Czechoslovak government into intervention so they could pounce. The only big difference is actually that the latter were much more reluctant and appeasing to the separatists. Which didn't help because annexation was the only goal for the nazi's anyway.
