From a Washington Post column by Max Boot headlined “Ukraine’s top general admits the war is stalemated. Now what?”

In warfare, attacking has always been harder than defending. The war in Ukraine demonstrates that it has become harder still in the digital age. The prevalence of drones makes it almost impossible to advance undetected, and the pervasiveness of precision-guided munitions — including attack drones — makes it easy to hit troops and tanks on the move.

The Russians discovered for themselves the difficulty of offensive warfare during their initial invasion of Ukraine — and again during more recent offensives in Bakhmut and now Avdiivka. Russian troops have been mauled in “meat grinder” attacks while barely advancing.
