The main issue seems to be absolutely atrocious timing of nuclear reactor maintenance. (which is just bad luck).

I sure as hell hope that the dynamic will increase in providing ukraine with the weapons required to end of the war far more quickly. From a geopolitical standpoint, making sure russia does not win this war or end it in a stalemate is absolutely vital for European stability.
Also, it could lead to further defence integration in europe. (this has already been fast tracked once the war started).
