The range would probably fit that kind of a theory as well. I do not see any reason to condemn Ukraine if the final results are going to be "misfired/stray rocket, ukrainian-fired, russian-made counter-rocketry". Defending a nation from complete annihilation is a perfectly valid reason to, well, defend.
It is clear that russian aggression has the potential to cause civilian suffering even outside Ukraine. And it does, as seen with grain trade. And there's only Russia to blame for it.
