That’s an interesting idea. I’m not sure that LACNIC would want to issue a ROA for RIPE IP space after RIPE issues an AS0 ROA, though. And you’d at least need some kind of time delay to give other RIRs and operators and chance to discuss the matter before allowing RIPE to issue the AS0 ROA, eg in my example mitigation strategy.

Evil RIR would have to replace an existing ROA with one that explicitly makes a route invalid, i.e. issue an AS0 ROA for specific member prefix. This seems like a pretty convoluted way to try and take a network offline.
