Firstly, this ridiculous counter-attack has been stopped already by the Russian forces. Ukrainians and foreign mercenaries have been destroyed almost completely (1000+ dead). Russian army are liberating remaining villages captured previously by Ukrainian occupiers. It's already clear that this pathetic offensive won't reach the Kursk nuclear powerplant neither will it reach the city of Kursk.
The reason for this useless waste of troops and armored vehicles? Most probably Ukraine is trying to strengthen their positions before the rumored peace talks as well as to slow down Russian advances in the East.
But, there's also another side to this incident, obscure to retarded Ukrainian trolls like yourself: Belarus, which is in a military alliance with Russia is now obliged to assist Russia militarily. It's almost 70k men strong army is ready to attack anywhere along the Belarus/Ukraine border (Kiev is only 260km away from the Belarussian border btw). You probably suck at chess, my little friend: you can't see beyond the end of your nose.
Well, let’s see how alive the Collective Security Treaty is, of which the Russian Federation and Belarus are members. Lukashenko is not such an idiot as he seems at first glance. He was confident that Russia would quickly capture Ukraine after the invasion in February 2022 and therefore provided his territory to Russian troops to attack Kyiv. But after the Russian occupiers were driven out of central and northern Ukraine in April, Russia failed to persuade Lukashenko to launch a direct attack on Ukraine.
Lukashenko will never give the order for his troops to invade Ukraine, because it would be fatal for his regime and he understands this. And not only because his 70,000-strong army will be immediately defeated, but because most likely a significant part of the Belarusian troops will go over to the side of Ukraine. The people of Belarus do not consider Ukrainians their enemies and after the overthrow of dictator Lukashenko, friendly relations will be resumed between these states.
Now, at the request of Russia, Lukashenko is trying to increase tension on the border with Ukraine so that Ukraine is forced to keep part of its troops near the border of Belarus and not transfer them to the Kursk region of Russia. Lukashenko will not agree to anything more.
And the offensive of the Ukrainian Armed Forces in the Kursk region of Russia continues. In just a few days, the Ukrainian Armed Forces “liberated” more territory than Russia did during the entire period of the offensive on the Kharkov region from May 10th.
