What you are warning about has already been happening since March 2022, when Russian occupation forces seized the Zaporozhye nuclear power plant,
Russia is already a nuclear threat. Capturing a nuclear power plant doesn't make it into one.
Ukraine is not a nuclear threat. Capturing a nuclear power plant with armed forces makes it into one.
That's the difference. In technical terms it is one step higher on the escalation ladder.
So, yesterday, on August 11, the occupiers intentionally or through negligence started a fire at this nuclear power plant,
Another reason why capturing "Kurskaya nuclear power plant" is a stupid idea. As I pointed out any nuclear incident whether intentional or not could set forth bad follow up events. In worse case scenario Russians could blow it up with Ukrainian forces inside, blame it on Ukraine, use it as an excuse to use their tactical nukes on Ukraine!
In my opinion, and this is now being actively discussed on social networks, it would be nice for the Ukrainian Armed Forces to take possession of this nuclear power plant and then exchange it for the Zaporizhzhya Nuclear Power Plant of Ukraine in order to prevent a major catastrophe on it in the future from the retreating Russian occupiers.
Exactly as I said above. But only on paper.
In reality I already explained the problems with that in my previous comment.
