Moscow reported on Friday, May 26, Ukrainian bombing of the Belgorod region, bordering Ukraine, for the fifth consecutive day. These strikes are a battlefield-shaping tactic, an indispensable preamble to any offensive.
An offensive against a fortified opponent necessarily involves a phase of "modeling" the battlefield. To do better than the autumn offensives, it is better for the Ukrainians to wait until all the planets are aligned and that the Western weaponry is well in place to go on the offensive.
