Russia claims that the Kakhovka dam on the Dnipro River was destroyed by Ukrainian shelling. The Ukrainian leadership claims that Russian units blew them up. What is true cannot be said with certainty under the current circumstances.
But one thing is undeniable: the cause of this catastrophe is Russia's war of aggression against Ukraine. And it is just as obvious, given the war so far, that the Russian occupiers would be unscrupulous enough to deliberately bring about such a disaster.
There are many good reasons to look for the perpetrators in Russia. If anyone should have any military benefit from the large-scale floods, it is the Russian troops. For the Ukrainian army, they only create additional difficulties in its expected offensive.
In the lowlands of agitation
Moreover, there is no reason why Ukrainians should destroy their own country. Unlike Russia's leadership, Ukraine's leadership also has a reputation to lose – a reputation that is vital to it because it depends on what support the country gets from the West.
Since the Kremlin has had to realize that Russian troops will not succeed in occupying Ukraine and overthrowing its democratically elected leadership, its warfare has been aimed at depriving Ukraine of its ability to survive as a state. Vladimir Putin's propagandists rant day after day about the need for the complete destruction of the country, which the master in the Kremlin has called "anti-Russia".
In the lowlands of the agitation of Russian state media, the attack on Ukraine is rarely justified by the "liberation" of Ukrainians from a "Nazi regime" and similar lies. Instead, blatant fantasies of annihilation can often be heard there. It would not be surprising if they had taken shape on the Dnipro.
