Hasn't Russia chosen to attack a nuclear power plant in their recent aggression? Unless you're thinking of a more destructive kind of attack, I probably shouldn't be counting on international intervention.
I don’t mean to suggest it alone would tip the scales. And I agree the hope for international intervention is dimmer than it ever has been. But it would be one thing on the scales, as it has been in Ukraine as well. While there has not been direct military intervention in Ukraine, the support that has been provided relies on political popularity, and Russia’s endangering of Zaporizhzhia has contributed to the disdain of and attention towards Russia’s invention.
