Ukraine

I agree but doesn't that just underline the stupidity of blowing up Kakhovka Dam or the fact that it was done to prepare for a imminent defeat?

Southern Ukraine and Crimea will become economical disasters because of this and if Russia was able to control them, they'd only have strategic value against Ukraine and the Black Sea region. Monetarily, they will be a black hole for years to come and living there won't be easy for the civilians.

So it only really makes sense to destroy the area in case you know you are about to lose it. Of course that is to presuppose that the decision was well planned in advance rather than based on feeling and miscalculations, which could very well be the case. The incompetence at play here is amazing, so it's very possible no one really wanted catastrophe on this level, but idiotic decision were made on whim or based on biased data.

Whatever the case, let's hope Ukraine prevails!
