Ukraine’s invasion (of Kursk) was a major strategic blunder, which will accelerate its defeat.
The key determinant of success in a war of attrition is the casualty-exchange ratio, not capturing territory, which Western commentators obsess over. The casualty-exchange ratio in the Kursk offensive decisively favours Russia for two reasons. First, it has caused relatively few Russian casualties because Ukraine’s army effectively overran undefended territory. Second, once alerted to the attack, Moscow quickly brought massive airpower to bear against the advancing Ukrainian troops, who were in the open and easy to strike. Unsurprisingly, the attacking forces lost many soldiers and a huge proportion of their equipment.
To make matters worse, Kyiv removed top-notch combat units from the front lines in eastern Ukraine — where they are desperately needed — and made them part of the Kursk strike force. This move is tilting the already lopsided casualty-exchange ratio on that critically important front further in Russia’s favour. It is no wonder — given what a foolish idea the Kursk incursion is — that the Russians were caught by surprise.
